2FAS Authenticator App

2FAS is a well-crafted and convenient application that protects access to your online services and accounts. Often a single password for your Facebook or Instagram account isn’t enough to protect your sensitive information. The 2FAS Authenticator App generates additional one-time codes called Time-based One-time Passwords (TOTP) for your account. By creating these codes offline and changing them every 30 seconds, 2FAS dramatically increases the security of your information.

Two Factor Authentication

2FA doubles an account’s security by using a Time-based One-time Password (TOTP) in addition to your regular password. Our 2FAS Authenticator App generates the TOTP on the user’s device to increase security and accessibility.

2FAS Backup

We’ve developed a remote backup service (RBS) function that allows you to store service keys in a secure, cloud-based backup so you can recover them if you lose your phone. This feature also allows you to generate codes on different devices.

Authorize with Touch ID or Face ID

Confirm your identity with 2FAS using Touch ID or Face ID to easily access the one-time tokens generator required to log in to your online accounts.

Sync across devices

Once configured with an online account, the 2FAS app works efficiently on various mobile devices and allows you to log in from several devices at once.

No password stored

The application generates Time-based One-time Passwords (TOTP) that are stored on the user’s phone without internet access. This solution dramatically increases login security.

Works for IOS and Android

The 2FAS Authenticator App is free and available to both Android and iOS users through Google Play or the App Store.

2FAS Backup: How to Avoid Account Lockouts When You Lose Your Phone

With our 2FAS Backup system, you can store all your service keys in the cloud and access them when needed.

In case you lose or damage your phone, simply install 2FAS Authenticator App on your new device to access your service keys. Your keys will allow you to instantly restore all your service accounts (e.g. Facebook) on your new device so you never get locked out. This is also facilitated by cross-device synchronization which enables you to generate tokens on multiple devices. 2FAS Backup is optional and you can turn it on and off at any time.
