How to use the 2FAS Auth Browser Extension

Privacy and security are non-negotiable

Consistent end-to-end encryption

All communication between your mobile device and your browser is always end-to-end encrypted.

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. Just the way it should be with everything regarding privacy.

Open-source project

You can easily take a look at our code - reflecting our transparent and user-first approach. Check out our GitHub repository and delve deep into the intricacies of the browser extension back-end.
