Time-based one-time password (TOTP) generation for two-factor authentication across hundreds of services

Free app, works with: Google, Microsoft, Facebook, Twitter, GitHub, Dropbox, crypto exchanges, password managers

TOTP secret seeds, QR codes, 6-digit time-based codes, account entries, cloud backup (Google account sync - new feature)

Google Authenticator added cloud backup in April 2023. This feature is NOT enabled by default. Must be turned on manually to prevent total loss if phone is lost or you die.

New export feature (2023) allows transferring codes to another device. Use this to create offline backup for inheritance.

Google Authenticator is just a code generator. Recovery codes are your REAL backup if app fails or phone dies. Store codes in password manager.

If cloud backup not enabled, your family needs your phone PIN/password to open Google Authenticator app and see codes.

1Password, Bitwarden, and LastPass offer built-in TOTP/2FA code generation. Consolidates passwords + 2FA codes in one inheritance-ready location.
