Bitwarden Authenticator is a standalone app that is available for everyone, even non-Bitwarden customers.
In its current release, Bitwarden Authenticator generates time-based one-time passwords (TOTP) for users who want to add an extra layer of 2FA security to their logins.
There is a comprehensive roadmap planned with additional functionality.
Available for iOS and Android
TOTP in the Bitwarden Vault is a paid feature. The standalone app is free, and doesn’t even require a Bitwarden account.
This allows free tier users a way to use TOTP without upgrading, and without needing to trust Google Authenticator or something else.
