2FAS Pass Android is the open-source Android implementation of the 2FAS password-protected authenticator and secure vault project, which blends two-factor authentication (2FA) token generation with a secure vault for managing verification codes and potentially other sensitive credentials. While specific repo details vary by the community project, in the broader 2FAS ecosystem the Android clients are designed to generate TOTP (time-based one-time passwords) and HOTP codes for users’ accounts, helping them meet modern multi-factor authentication needs through a simple, private user interface that works offline and without needing an account. The app supports scanning QR codes to add new authentication tokens, allows local encrypted storage of secrets, and can restore tokens from backups or synced devices. 2FAS focuses on privacy and simplicity—tokens aren’t sent to third parties, metadata isn’t stored externally, and users can secure the app with biometrics or passcodes.
