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
To be fair, a lot of sites that I consider “low security” are starting to mandate 2fa. Password manager is perfect place for these, I have more going on in my life than copying numbers from device 1 to device 2 to get my garbage picked up.
Yeah,when I got more than 30 totp accounts, I gave up on keeping them separate. Its still better than 1FA.
