Authman

Cross-Platform 2FA TOTP Made Easy

Authman 2FA is a free, secure and open source cross-platform app to help you manage your 2-step authentication tokens on iOS, Android and desktop, and securely sync them between devices.

🔐

Secure

Authman sign-in your account by secure remote password (SRP) protocol, your plain password will never be stored or transmitted to server.

🔑

Encryption

Authman encrypted your tokens by a key which is derived from your master password. You must provide your password when everytime you access the app. Since your password will never store in memory or server, no one can fetch your plain 2FA tokens.
