Fast 2FA is a lightweight and secure extension that generates Time-Based One-Time Passwords (TOTP) directly in your browser.

This extension is designed as an addon to "2fas" Android mobile application https://play.google.com/store/search?q=2fas&c=apps

You first export 2FA tokens from the 2fas application and then import them securely inside Fast 2FA.

Designed for speed and privacy, it keeps your 2FA codes accessible without needing to reach for your phone.

NOTE: this extension is not affiliated with the Android App "2fas"

Key Features:

- Secure Encryption: All your 2FA secrets are encrypted with a master password that only you know. Your data never leaves your browser unencrypted.
