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
Not open source, and I believe an account is required.
Also doesn’t allow you to export so you can’t switch to another service
Also they have weird behind the scenes integrations into accounts even if they are just supposed to be regular 2FA. You can read stories about Twitch not playing well with other 2FA until 30 days after you remove Authy. I don’t want those kind of shadow integrations and I should be allowed to switch apps as I see fit
Uhg… Didn’t know that part. So frustrating.
