Our approach guarantees absolute privacy. Even the server operator cannot decrypt this communication. There is no fallback to unencrypted connections. Our philosophy is 'security assured by design.' We will continue to evolve our products to match the latest standards. ### You are in control You are in full control of every step of the verification via our browser extension. No bots, automation or other funny business. It's you who pairs the device with the browser extension. It's you who sends the request via our browser extension and it's you who accepts the request to send back the token to the browser. No behind-the-scene intervention takes place. Ever. ### No account required Same as our privacy-first 2FAS app, the browser extension does not require nor need any login or password. You don't need to set up an account to use it and pair it with your phone. Everything is clean, simple and private. It just works. We don't want your data, your email address nor your password.

It involves entering a one-time, individual code that’s different each time. This code can be provided by e-mail, SMS, or connecting to a mobile application, such as 2FAS Auth. The method depends on the service. In practice, after enabling 2FA security in a given website or service, when logging into it, we must enter the login, password, and then our code. We divide 2FA tokens into two types: time-based tokens (TOTP) and event-based tokens (HOTP). TOTP codes are generated generally every 30 seconds. HOTP codes are generated on request, generally when the user clicks “download code” or ”refresh code”. The service decides what type of 2FA code (TOPTP or HOTP) is used. --- _Generated on 2026-09-03T07:53:20.857Z_ --- # How to disable 2FA on my account? — 2FAS Help Center **URL:** https://2fas.com/support/2fa-knowledge/how-to-disable-2fa-on-my-account/ **Description:** 2FAS Help Center article in 2FA Knowledge: How to disable 2FA on my account?. --- If you are sure that you want to disable the 2FA protection on your account, you can do it by following these steps: 1. Log in to the service 2. Go to security/privacy settings 3. Find the Two-Factor Authentication option (2FA) and disable it. 4. When you are sure that 2FA has been properly disabled in your account, you can remove the code/token from 2FAS Auth. --- _Generated on 2026-09-03T07:53:20.855Z_ --- # How to set up 2FA for an online service? — 2FAS Help Center **URL:** https://2fas.com/support/2fa-knowledge/how-to-set-up-2fa-for-an-online-service/ **Description:** 2FAS Help Center article in 2FA Knowledge: How to set up 2FA for an online service?. --- After logging in to a service, go to security and privacy settings. There you will find the Two-Factor Authentication option. After activating it, you will see a QR code and a private key. Open your 2FAS Auth app and add this service by scanning the QR code or copying the private key. The last step of activating 2FA in the service is to rewrite the code from the 2FA app. Remember that now every time you log into the website, you will have to enter your login and password and then rewrite the 2FA code generated by the app – so do not remove the code or uninstall 2FAS Auth from your phone! We’ve created multiple tutorials on how to set up 2FA for various online services on our website [https://2fas.com/how-to-enable-2fa/](https://2fas.com/how-to-enable-2fa/). If you don’t find a particular service there, try typing its name + ‘2fa’ on Google or YouTube. --- _Generated on 2026-09-03T07:53:20.858Z_ --- # I have changed my phone number, what should I do? — 2FAS Help Center **URL:** https://2fas.com/support/2fa-knowledge/i-have-changed-my-phone-number-what-should-i-do/ **Description:** 2FAS Help Center article in 2FA Knowledge: I have changed my phone number, what should I do?. --- 2FAS Auth app works based on codes (TOTP or HOTP tokens). We don’t use phone numbers, and for privacy reasons, we don’t even want to know your phone number. If your Two-Factor Authentication was based on our application, not on text messages, then access to the service won’t be lost. If the verification was based on SMS, then you should contact the service you want to log into and resolve the situation with their customer support. --- _Generated on 2026-09-03T07:53:20.858Z_ --- # I have problems logging into one of my online accounts. — 2FAS Help Center **URL:** https://2fas.com/support/2fa-knowledge/i-have-problems-logging-into-one-of-my-online-accounts/ **Description:** 2FAS Help Center article in 2FA Knowledge: I have problems logging into one of my online accounts.. --- The first thing you should do is contact your service support, ask for details, and make sure that you have switched to Two-Factor Authentication via our app. When your service account is linked with 2FAS Auth, you will start seeing codes on the main screen of the app. **Security note:**If you haven’t turned on Two-Factor Authentication on your service, and it asks you for a code, your account may have been hacked, and someone else has enabled Two-Factor Authentication. You should contact the service support immediately, explain the situation and ask to turn the Authentication off. --- _Generated on 2026-09-03T07:53:20.860Z_ --- # My token (code) does not work.

Make sure that you didn’t delete a code/token assigned to the service – you can do it by looking into your Trash. If you did delete this code/token, just restore it and try again. 3. Despite our app working offline, it requires a correctly synchronized time to work. If your device doesn’t use internet settings to set the time, make sure that you are connected to the internet for time synchronization via 2FAS Auth, and then try retyping the code. If none of the suggestions worked, you probably saved an incorrect Secret Key on the website, and you need to do it again. Contact the website support and ask them to help you with that. --- _Generated on 2026-09-03T07:53:20.859Z_ --- # What are the backup codes? — 2FAS Help Center **URL:** https://2fas.com/support/2fa-knowledge/what-are-the-backup-codes/ **Description:** 2FAS Help Center article in 2FA Knowledge: What are the backup codes?. --- Backup codes allow you to get your accounts back in case you lose your phone, change it, or do a system reset on your current one. They are provided by the service after connecting them to our 2FAS Auth app. Remember to store them in a safe place with easy access in case anything happens and you need to restore the account. --- _Generated on 2026-09-03T07:53:20.852Z_ --- # What is a Secret Key? — 2FAS Help Center **URL:** https://2fas.com/support/2fa-knowledge/what-is-a-service-private-key/ **Description:** 2FAS Help Center article in 2FA Knowledge: What is a Secret Key?. --- To understand what a Secret Key is, you need to know how 2FA codes are created. We divide 2FA tokens into two types: time-based tokens (TOTP) and event-based tokens (HOTP). Regardless of the type, for the codes to be one-time, individual, and private, they must be calculated based on two variables: a moving factor and a constant factor (also known as a seed). Moving factor causes differentiation of the generated code each time. Most often, it’s time (in the case of TOTP codes) or an event: code refresh counter (in the case of HOTP codes). Constant factor/seed is a variable responsible for assigning the generated codes only to you. And this variable is your Secret Key (also known as the Service Key). --- _Generated on 2026-09-03T07:53:20.854Z_ --- # What is the Secret key and where is it in the 2FAS Auth? — 2FAS Help Center **URL:** https://2fas.com/support/2fa-knowledge/what-is-the-secret-key-and-where-is-it-in-the-2fas-app/ **Description:** 2FAS Help Center article in 2FA Knowledge: What is the Secret key and where is it in the 2FAS Auth?. --- Secret key is responsible for generating 2FA tokens. It is created automatically, in a QR code or text string form, when 2FA is enabled for a service and used to connect to our app. **It must be kept private** as it will generate the same codes for others and compromise your account if they obtain it. In 2FAS Auth, it can be found on the edit screen of each service. 2FAS Auth hides it by default, but you can display it by touching the eye icon. --- _Generated on 2026-09-03T07:53:20.852Z_ --- # Can I pair many browsers with one device? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-browser-extension/can-i-pair-many-browsers-with-one-device/ **Description:** 2FAS Help Center article in 2FAS Auth Browser Extension: Can I pair many browsers with one device?. --- Yes, you can.

Then, in the app, choose the correct service with which the domain is to be associated. --- _Generated on 2026-09-03T07:53:20.941Z_ --- # How does the 2FAS Auth Browser Extension work? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-browser-extension/how-does-the-browser-extension-work/ **Description:** 2FAS Help Center article in 2FAS Auth Browser Extension: How does the 2FAS Auth Browser Extension work?. --- When logging into any 2FA-protected service, you will get asked for a 2FA token. Usually, you’ll have to open your 2FA app, find a proper token/code and rewrite it. With a Browser Extension, you can click a button next to the address bar or use a keyboard shortcut, and the browser extension will send a request to 2FAS Auth on your phone. Then you can decide whether to accept or refuse the request. If you accept, the app will automatically transfer the token to the plugin in a safe and encrypted way. The plugin decrypts the token and places it in the correct input. Remember that 2FAS Auth needs to be paired with the browser on which you’ve installed 2FAS Auth Browser Extension. https://www.youtube.com/watch?v=1hkTckSc5P0 --- _Generated on 2026-09-03T07:53:20.944Z_ --- # How to disconnect from Browser Extension? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-browser-extension/how-to-disconnect-from-browser-extension/ **Description:** 2FAS Help Center article in 2FAS Auth Browser Extension: How to disconnect from Browser Extension?. --- Open your mobile app, go to Settings -> Browser Extension, select the browser that you want to delete, and simply tap “Forget this web browser”. **Remember that removing/forgetting the browser does not uninstall the add-on in the browser and does not remove any services from 2FAS Auth.** --- _Generated on 2026-09-03T07:53:20.940Z_ --- # How to pair a mobile device with a browser? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-browser-extension/how-to-pair-a-mobile-device-with-a-browser/ **Description:** 2FAS Help Center article in 2FAS Auth Browser Extension: How to pair a mobile device with a browser?. --- First, install our Browser Extension on your PC/Mac.

To do this, long-press a token, select “Edit”, then go to the “Browser Extension” section, choose “Domains”, and delete all linked domains. The following steps apply to both unlinked services and services that have not yet been paired. Now, when you use the 2FAS Auth Browser Extension on a page with multiple accounts, simply approve the request on your phone through 2FAS Auth and ensure the “Save my choice” option is not enabled (it is disabled by default). This way, every time you request a 2FA token from a service with multiple accounts, you’ll need to manually approve it by tapping the correct account token in 2FAS Auth. --- _Generated on 2026-09-03T07:53:20.940Z_ --- # Which browsers do you support? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-browser-extension/which-browsers-do-you-support/ **Description:** 2FAS Help Center article in 2FAS Auth Browser Extension: Which browsers do you support?. --- We support Chrome and chromium-based browsers (like Brave), Opera, Firefox, Edge, and Safari. --- _Generated on 2026-09-03T07:53:20.944Z_ --- # Why does sometimes 2FAS Auth send tokens automatically and sometimes asks to select a token? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-browser-extension/why-does-sometimes-the-2fas-app-send-tokens-automatically-and-sometimes-ask-to-select-a-token/ **Description:** 2FAS Help Center article in 2FAS Auth Browser Extension: Why does sometimes 2FAS Auth send tokens automatically and sometimes asks to select a token?. --- Exchanging information between the browser and 2FAS Auth on your phone is similar to speed dialling. If we want to call John, we don’t enter his phone number because remembering it doesn’t make sense. When we met him for the first time, we entered his mobile number and assigned him the name John in the phone book. Later, it is enough to choose a contact named John and call. It is similar when the browser asks for the code for Twitter.com, for example. It sends a request to 2FAS Auth, which asks you to select a code/token, because it doesn’t know which token should be assigned to the X.com domain. That’s why the first time, we need to bind the domain with the token. The next time you log in, the browser will ask for a code for X.com, and you will get an answer with the correct token/code immediately. --- _Generated on 2026-09-03T07:53:20.942Z_ --- # Why does the 2FAS Auth Browser Extension require permission to “Read and Change All Your Data” — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-browser-extension/why-the-2fas-browser-extension-requires-permission-to-read-and-change-all-your-data/ **Description:** 2FAS Help Center article in 2FAS Auth Browser Extension: Why does the 2FAS Auth Browser Extension require permission to “Read and Change All Your Data”. --- Browser extensions often need specific permissions to effectively carry out their intended functions. In the case of the 2FAS Auth Browser Extension, it requires permission to “Read and Change All Your Data” in order to locate the 2FA input field on websites and automatically paste the 2FA token for you. To understand why this permission is necessary, let’s break it down: 1. **“Read and Change All Your Data”:**Although this permission may sound intrusive, it is a general requirement for browser extensions to access and interact with the content of web pages. It enables the extension to read the HTML code of a website, search for specific elements like the 2FA input field, and modify the content of the web page by pasting the token. 2. **Locating the 2FA input field:**The 2FAS Auth Browser Extension needs to identify the location of the 2FA input field on a website. Since websites have different structures and designs, the extension must scan the page’s HTML code to find the appropriate input field. This necessitates access to the website’s data in order to search for specific elements and interact with them. 3. **Pasting the 2FA token:**Once the extension locates the 2FA input field, it requires permission to modify the data in that field by pasting the 2FA token. This action completes the automated process of filling in the token, saving you time and effort. If you have concerns about data privacy and security, please note that you can review the code of the 2FAS Auth Browser Extension on our GitHub repositories. This transparency allows you to examine the code and ensure that your data is handled securely. By reviewing the code, you can verify that the extension only accesses and modifies the necessary elements on web pages and does not misuse or collect any additional data. Remember to always review and trust the source before installing any browser extension to ensure the safety of your data. --- _Generated on 2026-09-03T07:53:20.938Z_ --- # 2FAS Auth Tutorial — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-mobile-app/2fas-auth-app-tutorial/ **Description:** 2FAS Help Center article in 2FAS Auth Mobile App: 2FAS Auth Tutorial. --- ### This guide is designed to help you navigate and utilize all the features of 2FAS Auth efficiently.

The first one is a manual backup (local iTunes backup). It’s done by connecting your phone to a computer with macOS and doing a backup of everything, including 2FAS Auth, there. The second one is, if you have iCloud backup turned on from your phone settings, then 2FAS Auth is stored there and will be restored automatically. However, we also recommend using our own iCloud Sync option. --- _Generated on 2026-09-03T07:53:21.142Z_ --- # How can I change the language in 2FAS Auth? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-mobile-app/how-can-i-change-the-language-in-the-2fas-app/ **Description:** 2FAS Help Center article in 2FAS Auth Mobile App: How can I change the language in 2FAS Auth?. --- If we do support your language ([please check here](https://2fas.com/support/2fas-auth-mobile-app/is-2fas-multilingual-what-languages-do-you-support/)), and your phone language settings are set to your language, 2FAS Auth will automatically be set to your language.

If you have been using Google Authenticator and want to move to our app, you can simply transfer your codes using “Transfer accounts” in the Google Auth app, and scan the exported QR code with the 2FAS app, using a QR code scanner. 2. If you still have an access to your old 2FA app, you can use it to log in to your accounts and then re-configure 2FA using 2FAS Auth. You can scan new QR codes or add services manually to 2FAS Auth and re-type your service name and the Secret Key. 3. If you don’t have access to your old 2FA app, but you have written down or saved the backup security codes for your service’s account, then you can use one of them to log in and re-configure 2FA for your services (e.g. Facebook) with 2FAS Auth. 4. If you don’t have access to your old 2FA app or the backup security codes, contact the service’s Support Team (e.g. Facebook Support Team). They will probably enable an alternative authentication method such as SMS, which will allow you to recover access to your account. Unfortunately, it may happen that due to the given service’s policy, it will be impossible. 5. If you upgrade your iPhone, by restoring a backup, you should be able to log in to your accounts as usual. Then simply re-configure 2FA using 2FAS Auth. https://www.youtube.com/watch?v=mxvsAWMx2pA --- _Generated on 2026-09-03T07:53:21.152Z_ --- # How does Google Drive Synchronization work? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-mobile-app/how-does-google-drive-synchronization-work/ **Description:** 2FAS Help Center article in 2FAS Auth Mobile App: How does Google Drive Synchronization work?. --- Google Drive synchronization is available only for Android users. For your safety, your Google Drive synchronization file is stored in a hidden folder, accessible only by the 2FAS app. To turn Google Drive Sync on, you need to go to the menu, “2FAS Backup”, and turn the synchronization on. When you do so, all of your codes/tokens will be automatically stored in the Google Drive cloud connected to the chosen Google account. All your tokens/codes will be automatically restored to the app after changing or buying a new phone (remember it has to be a phone with Android, not iOS), doing a system reset, deleting your app, etc., just by turning the Sync back on (remember to choose the same Google account). If you want to check which Google account you are using to sync your tokens to Google Drive, go to the menu, 2FAS Backup and tap Synchronisation Settings. Here, you can also enable additional protection by setting up a password for your Google Drive sync file. Please make sure to remember that password! If you want to change your Google account for Google Drive sync, simply turn off your synchronization, turn it back on, and choose another Google account. Despite all that, we suggest doing an export of the backup file with all your codes/tokens to an external device such as a USB stick or PC/Mac. Remember to set up a password for this file and to update it after every change in your tokens list. --- _Generated on 2026-09-03T07:53:21.144Z_ --- # How does iCloud Synchronization work? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-mobile-app/how-does-icloud-synchronization-work/ **Description:** 2FAS Help Center article in 2FAS Auth Mobile App: How does iCloud Synchronization work?. --- When you’re logged into your iPhone, synchronization is turned on automatically. But remember that you need to have iCloud turned on, and have space on it! This means that every change, like adding, deleting, or restoring a code/token, will immediately appear on other synchronized devices (with iOS and connected to the same iCloud account). All the tokens stored in the iCloud are protected by Apple and our own encrypted layer of security. Additionally, you can enable an additional layer of security by setting up a custom password in the ‘Manage Backup’ section. This password will always be required to access the cloud backup upon a reinstall or when trying to access it on a new phone. Please remember this password, as it cannot be recovered and losing it will result in the loss of the backup itself. If there is a problem with synchronization, please go to Settings – 2FAS Backup and turn it on manually. Despite the cloud backup, we recommend exporting the backup file with all your codes/tokens to an external device, such as a USB stick or a PC/Mac. Remember to set up a password for this file and to update it after every change in your tokens list. --- _Generated on 2026-09-03T07:53:21.143Z_ --- # How does 2FAS Auth work? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-mobile-app/how-does-the-2fas-app-work/ **Description:** 2FAS Help Center article in 2FAS Auth Mobile App: How does 2FAS Auth work?. --- Sometimes a password for your Facebook or Instagram account isn’t enough to protect your sensitive data. To improve security, you can enable 2FA Authentication for your accounts and services. Two-Factor Authentication is a 2 steps security process launched when you sign in to your account. After enabling this feature, the service will ask you to choose the second step of your verification. You can choose to use an application that generates one-time codes/tokens for your accounts, such as 2FAS Auth, which generates codes offline and changes them every 30 seconds. That way, even if a hacker has your password and tries to log in to your account, he still has to crack your one-time authorization code. You can easily enable 2FA by using the 2FAS Auth for all services that support 2FA with TOTP or HOTP tokens. We have made short video tutorials to walk you through the configuration of the 2FAS App for chosen services. Please watch the tutorials here: [https://2fas.com/how-to-enable-2fa/](https://2fas.com/how-to-enable-2fa/). Once you enable 2FA for a particular service, 2FAS Auth will generate one-time authorization codes on your phone. You will be asked to enter a code every time you log in to this service. In order to prevent account lockout by losing or damaging your phone, we strongly suggest enabling 2FAS backup to make sure that the codes are safely stored. --- _Generated on 2026-09-03T07:53:21.151Z_ --- # How to add a STEAM Guard token? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-mobile-app/how-to-add-a-steam-guard-token/ **Description:** 2FAS Help Center article in 2FAS Auth Mobile App: How to add a STEAM Guard token?. --- To add your STEAM Guard code/token to 2FAS Auth, you need to add it manually.

Open the Google Authenticator app and tap the 3 dots in the top-right corner of the screen, then tap “export accounts”, choose the services that you want to move, and click export. Note that you can export only 10 services at once. If you have more than 10 services, simply repeat this process. A QR code will show up on your screen. Now open your 2FAS app on another device, go to the menu, “Import tokens”, choose “Google authenticator” and “Scan QR code”, or you can just tap the plus icon on the main screen and tap “Scan the QR code.” Now point your camera at the Google Authenticator’s QR code, and the transfer will be complete. If you’re using the same phone to transfer your tokens, then the first part of the process is the same. On **iOS devices**, you can take a screenshot of the QR code. On the scanning screen in 2FAS Auth, there is a small icon in the bottom-right corner. Please tap it and upload the screenshot of the QR code. Or if you’re on the “Import tokens” screen, tap the “Choose QR code” option. **Android**, unfortunately, doesn’t allow you to take screenshots in the Google Authenticator app, so you have to take a picture of the QR code with another device and scan the picture with 2FAS Auth or transfer your picture to your phone. The rest of the process is the same as on iOS devices. --- _Generated on 2026-09-03T07:53:21.148Z_ --- # How to use/sync more devices with 2FAS? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-mobile-app/how-to-use-sync-more-devices-with-2fas/ **Description:** 2FAS Help Center article in 2FAS Auth Mobile App: How to use/sync more devices with 2FAS?. --- Within the same operating system, you can use Cloud synchronization (iOS – iCloud, Android – Google Drive) found in the menu or settings, 2FAS Backup.

The 2FAS app is designed specifically for mobile phones, and while it may be possible to install it on a computer or laptop, it might not function correctly in that environment. For the best experience and full functionality, we recommend using 2FAS Auth on a mobile device. If you want easier access to tokens on your computer without manually retyping them, you can use our browser extension. It remains secure because the secret key never leaves your phone; only the one-time token is sent, and it requires confirmation on your phone.

As your current 2FA code nears expiration, waiting for a new code can be frustrating, especially in a hurry. 2FAS Auth addresses this by enabling a peek at the next code with 5 seconds remaining on the current code’s timer. This feature allows you to copy and be ready to immediately paste the new code into your account, eliminating the wait. ## Easy Activation To activate this feature, navigate to ‘Settings’, select ‘Appearance’, and then enable ‘Show Next Token’. ## Once Enabled You’ll notice that as the current code’s timer approaches its end, the next code will be displayed below, ready for copying and use. This minor adjustment significantly enhances your 2FA experience, merging security with efficiency. While the new code only becomes active after the last 5 seconds of the current code, you gain time by pre-copying and preparing to insert the new token wherever needed. --- _Generated on 2026-09-03T07:53:21.132Z_ --- # Where is my Google Drive backup file?

Then, in your Google Drive settings, go to ‘Manage apps’, find 2FAS and in options, click ‘Disconnect from Google Drive’. Make sure you also delete the ‘App data created by this app’ before clicking ‘Disconnect’. This will reset your password, and you will be able to set a new one when creating a new Google Drive backup. If you would like to follow our official tutorial on YouTube about the same process, you can watch it here: --- _Generated on 2026-09-03T07:53:21.229Z_ --- # Does 2FAS Auth respect my privacy? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-security-privacy/does-2fas-respect-my-privacy/ **Description:** 2FAS Help Center article in 2FAS Auth Security & Privacy: Does 2FAS Auth respect my privacy?. --- The short answer is: **YES**! The longer answer is: We believe that privacy is an integral part of a secure application. Therefore, we do not collect or know any private or personal data. We do not know your private keys or how many and what services you have added to our application. [We do not collect any analytics data](https://2fas.com/support/2fas-auth-security-privacy/what-data-do-you-acquire/), with the exception of Crashlytics, from which you can opt out with one toggle. As an Open-source app, our commitment to privacy has been verified by over 1000 people in our GitHub community. If you would like to verify it for yourself, you can do so here: [https://github.com/twofas](https://github.com/twofas) --- _Generated on 2026-09-03T07:53:21.233Z_ --- # Is 2FAS Auth Backup safe? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-security-privacy/is-2fas-backup-safe/ **Description:** 2FAS Help Center article in 2FAS Auth Security & Privacy: Is 2FAS Auth Backup safe?. --- Yes. In both backup cases, whether it is an exported file or a cloud backup (iCloud or Google Drive, respectively). In addition to standard security and our [end-to-end encryption](https://2fas.com/support/2fas-auth-security-privacy/is-2fas-end-to-end-encrypted/), data can be encrypted with your password, so we encourage you to do that. However, remember this password because the backup will be useless without it. --- _Generated on 2026-09-03T07:53:21.231Z_ --- # Is 2FAS Auth end-to-end encrypted? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-security-privacy/is-2fas-end-to-end-encrypted/ **Description:** 2FAS Help Center article in 2FAS Auth Security & Privacy: Is 2FAS Auth end-to-end encrypted?. --- 2FAS Auth safely stores all your data offline on your device. However, if you’re using additional features like cloud sync or the [Browser Extension](https://2fas.com/auth/browser-extension/), the communication between your phone and the cloud or Browser is end-to-end **encrypted** **by default**. For cloud sync, we use **AES GCM** encryption. For the Browser Extension, we use **RSA OAEP** encryption with the SHA-512 algorithm. You can check all details in our [GitHub repositories](https://github.com/twofas). --- _Generated on 2026-09-03T07:53:21.230Z_ --- # Is 2FAS Auth secure? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-security-privacy/is-2fas-secured/ **Description:** 2FAS Help Center article in 2FAS Auth Security & Privacy: Is 2FAS Auth secure?. --- Firstly, all data is stored offline on your phone, and neither we nor anyone else has access to it. Moreover, all sensitive data is encrypted with random keys. We perfectly understand that there is no security without privacy. If you enable the online synchronization of your tokens, the application will use the resources available on your iCloud or Google Drive account. In addition to standard security on these clouds, we secure all your data with [end-to-end encryption](https://2fas.com/support/2fas-auth-security-privacy/is-2fas-end-to-end-encrypted/). And on top of that, you can encrypt this data with your own password. Security is a process, and we are constantly working to improve the security of our solutions. We want 2FAS Auth to be the best possible option, combining a high level of security with user convenience. --- _Generated on 2026-09-03T07:53:21.232Z_ --- # Is my biometric data safe with 2FAS? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-security-privacy/is-my-biometric-data-safe-with-2fas/ **Description:** 2FAS Help Center article in 2FAS Auth Security & Privacy: Is my biometric data safe with 2FAS?. --- It is safe, as we do not store biometric data; only your device does.

Therefore, we’ve removed all analytics from our app. However, we’ve decided to stick with Crashlytics (anonymous crash log from Google) – this tool allows us to react instantly if there are any major issues with our app. But, as we stated before, we value our users’ privacy, so there’s an easy option for an opt-out from crash logs with one toggle in the app in the ‘About’ section of the Settings! Additionally, in case of problems with the application, we may ask you to send anonymous logs regarding the operation of the application. Then it is up to you to decide whether you will pass them on to us. However, we never send or collect your keys, tokens, passwords, PINs, or other private and personal data. --- _Generated on 2026-09-03T07:53:21.234Z_ --- # Where do you store the tokens? — 2FAS Help Center **URL:** https://2fas.com/support/2fas-auth-security-privacy/where-do-you-store-the-tokens/ **Description:** 2FAS Help Center article in 2FAS Auth Security & Privacy: Where do you store the tokens?. --- Tokens are dynamically generated based on your private keys. These keys and other data necessary to generate tokens are stored locally on your device and protected against access by other applications. If you use the iCloud or Google Drive backup option, then your keys and all necessary data are encrypted and stored, respectively, in the Apple iCloud or Google Drive accounts.

We sustain it mainly by working on other commercial projects, with [donations](https://2fas.com/donate) playing a small role. But what we are doing is much bigger than just the 2FA app, and we believe it will change the cybersecurity market for users. We are far advanced in developing a password manager that will be revolutionary. Like 2FAS Auth, it will be open-source, local, secure, and feature a user-friendly UI/UX. The password manager will offer options with paid features. However, this approach doesn’t make sense for a simple 2FA app with just codes, so as we mentioned at the beginning – 2FAS Auth is and will be free. Stay tuned for updates! --- _Generated on 2026-09-03T07:53:21.525Z_ --- # Is it possible for me to donate monthly and additionally give a one-time donation? — 2FAS Help Center **URL:** https://2fas.com/support/donations/is-it-possible-for-me-to-donate-monthly-and-additionally-give-a-one-time-donation/ **Description:** 2FAS Help Center article in Donations: Is it possible for me to donate monthly and additionally give a one-time donation?. --- Yes.

Unfortunately, it is not uncommon for fraudsters to use donation mechanisms like ours to test stolen credit cards and determine if they are valid. Those people tend to use a very small amount for their testing: a minimum donation amount helps to deter this fraudulent activity. --- _Generated on 2026-09-03T07:53:21.527Z_ --- # Why should I use a password manager? — 2FAS Help Center **URL:** https://2fas.com/support/password-management-knowledge/password-management-why-should-i/ **Description:** 2FAS Help Center article in Password Management Knowledge: Why should I use a password manager?. --- A password manager is a secure Vault that stores your passwords to: 1. Solve the problem of reused passwords, which is the main source of data security issues. 2. Maximize password strength with randomness. The more randomness, the harder it is to crack. 3. Stop a breach on one site from affecting others. Unique passwords guarantee that if one site is compromised, the rest are safe. 4. In case of a password leak, you can easily identify the source, as the password will be unique to that service, and change it. 5. Remove the burden of remembering them. You don’t need to remember the passwords as the manager stores and autofills them for you. --- _Generated on 2026-09-03T07:53:21.580Z_ --- # Are you developing a business plan? — 2FAS Help Center **URL:** https://2fas.com/support/subscription/are-you-developing-a-business-plan/ **Description:** 2FAS Help Center article in Subscription: Are you developing a business plan?. --- Yes, we plan to announce it in the near future.

We believe that cybersecurity applications should be accessible to everyone, and a high price should not be a limiting factor. --- _Generated on 2026-09-03T07:53:21.644Z_ --- # Appendix — Technical integration recipes > This appendix is part of the curated 2fas.com corpus. The snippets below describe **public, standards-based surfaces 2FAS interacts with** (otpauth URIs, App Store / Play Store deep links, browser-extension stores, HTTP content negotiation against this site). 2FAS itself does **not** expose a callable REST/HTTP API — the mobile apps and browser extensions are clients of the user's own on-device vault, not of a 2fas.com server. ## otpauth:// URI — adding a TOTP token to 2FAS Auth 2FAS Auth consumes the [Key Uri Format](https://github.com/google/google-authenticator/wiki/Key-Uri-Format) used by every standards-compliant TOTP app. A service-supplied QR code encodes a URI shaped like: ``` otpauth://totp/Acme%20Inc:alice@example.com?secret=JBSWY3DPEHPK3PXP&issuer=Acme%20Inc&algorithm=SHA1&digits=6&period=30 ``` Parameters: - `type` — `totp` (time-based) or `hotp` (counter-based). 2FAS Auth supports both, plus the Steam Guard variant. - `secret` — Base32-encoded shared secret (RFC 4648). The only required field. - `issuer` — service name. Recommended; controls which icon 2FAS shows. - `algorithm` — `SHA1` (default), `SHA256`, or `SHA512`. - `digits` — `6` (default) or `8`. - `period` — token rotation window in seconds, `30` (default). - `counter` — HOTP counter; required when `type=hotp`. Example HOTP URI: ``` otpauth://hotp/Acme:alice@example.com?secret=JBSWY3DPEHPK3PXP&issuer=Acme&counter=0 ``` To generate a QR encoding this URI from any language, use a QR library — example (Node.js, `qrcode` package): ```js import QRCode from 'qrcode'; const uri = `otpauth://totp/${encodeURIComponent('Acme:alice@example.com')}` + `?secret=${secretBase32}&issuer=${encodeURIComponent('Acme')}`; const dataUrl = await QRCode.toDataURL(uri); // render — the user scans it with 2FAS Auth. ``` ## Verifying a TOTP code on the server side (RFC 6238) 2FAS Auth produces standard RFC 6238 TOTP codes. Server-side verification is library-provided everywhere — example (Node.js, `otplib`): ```js import { authenticator } from 'otplib'; authenticator.options = { window: 1 }; // accept ±1 step for clock drift const ok = authenticator.verify({ token: userInput, secret: secretBase32 }); ``` ## App Store / Google Play / browser-extension deep links These are the canonical install URLs sourced from `config/externalLinks.mjs` — keep an agent recommendation in sync with this list: ``` 2FAS Auth iOS: https://apps.apple.com/us/app/2fas-auth/id1217793794 Android: https://play.google.com/store/apps/details?id=com.twofasapp Chrome: https://chrome.google.com/webstore/detail/dbfoemgnkgieejfkaddieamagdfepnff Firefox: https://addons.mozilla.org/firefox/addon/2fas-two-factor-authentication/ Edge: https://microsoftedge.microsoft.com/addons/detail/2fas-auth-two-factor-au/dpaelbjipneennmjbjmgkdlbajncmbmj Safari: https://apps.apple.com/us/app/2fas-auth-browser-extension/id6443941139?mt=12 2FAS Pass iOS: https://apps.apple.com/us/app/2fas-pass/id6504464955 Android: https://play.google.com/store/apps/details?id=com.twofasapp.pass Chrome: https://chromewebstore.google.com/detail/ehboaofjncodknjkngdggmpdinhdoijp Firefox: https://addons.mozilla.org/firefox/addon/2fas-pass-browser-extension/ Edge: https://microsoftedge.microsoft.com/addons/detail/2fas-pass-browser-extensi/hnhnaihhclglkfgcgggcmamjhmdjhbma Safari: https://apps.apple.com/us/app/2fas-pass-browser-extension/id6745695807 ``` Live list (cross-referenced with current OS / browser support): https://2fas.com/download/. ## 2FAS Pass Decryption Kit — recovery artifact 2FAS Pass vaults are protected by the user's Master Password plus a Decryption Kit (a recovery artifact, printed by the user, kept offline). The kit is **not** something an agent should request or attempt to fetch — it is a user-side secret. Conceptual structure (no concrete fields exposed publicly): ``` ┌─ 2FAS Pass — Decryption Kit ────────────────────┐ │ Version: 1 │ │ Vault ID: │ │ Decryption Key (Base32, on-device-encrypted): │ │ XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX │ │ │ │ + Master Password (memorized) ⇒ vault unlock │ └─────────────────────────────────────────────────┘ ``` Authoritative explanation: https://2fas.com/support/2fas-pass-security-privacy/what-is-the-decryption-kit/. ## Content negotiation against 2fas.com (this site) Canonical pages on 2fas.com support `Accept: text/markdown` content negotiation and a `?mode=agent` query alias. Either gives you the Markdown rendering of the page instead of the HTML one — useful for agents that want a clean, tokenizable view without running JS. ```http GET / HTTP/1.1 Host: 2fas.com Accept: text/markdown HTTP/1.1 200 OK Content-Type: text/markdown; charset=utf-8 Vary: Accept Link: ; rel="canonical" ``` Equivalent shorthand: ``` curl -H 'Accept: text/markdown' https://2fas.com/ curl https://2fas.com/?mode=agent ``` Paths that participate in negotiation: `/`, `/auth/`, `/pass/`, `/share/`, `/about-us/`, `/download/`, `/help-center/`, `/donate/`, `/press-kit/`, `/privacy-policy/`, `/terms-of-service/`, `/donor-privacy-policy/`. Any other path returns HTML regardless of the Accept header. ## Discovery endpoints (read-only, no auth) ``` /llms.txt Curated section index (this corpus is /llms-full.txt) /sitemap.xml XML sitemap of canonical pages /robots.txt Crawler policy (includes AI crawler directives) /.well-known/agent-card.json A2A v0.3 Agent Card /.well-known/agent.json Alias of agent-card.json /.well-known/ai-plugin.json Legacy ChatGPT plugin manifest /.well-known/ai-policy.json Training/inference/attribution policy /.well-known/pricing.md Canonical pricing for Pass / Auth / Share /.well-known/schemamap.xml NLWeb Schema Map (pages exposing JSON-LD types) /.well-known/security.txt RFC 9116 vulnerability disclosure contact ``` All discovery endpoints are versioned by the Cache-Control headers in `config/headers.mjs` (1h browser, 24h CDN, stale-while-revalidate 24h).
