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
This new Bitwarden 2FA does backup and restore! It was also important to me, as I had a phone stolen one time and without my backed up “emergency codes”, I’d been SOL! :)
