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
It’s extremely convenient and not particularly safe. I love it, my FBI agent loves it, and my Russian hacker friend loves it too.
Why do you think its not safe? If you trust bitwarden to protect your passwords what exactly do you think is going to happen?
Even if bitwarden is compromised in someway in the future, all that data is still encrypted and would still be highly unlikely to actually be accessed in any usable form.
The only risk is if you use a bad master password. Which is the biggest risk of using a password manager regardless.
I think a bigger concern is if someone managed to access bitwarden on a logged in instance. Think, leaving your laptop open, or someone steals it from you. If theres two apps for logging then both apps need to be accessible/compromised.
The point of 2FA/MFA is that you need two separate things in order to gain access. By having them both be the same then suddenly the attacker only needs to get one factor. Sure, it’s probably low risk, but it’s still risk.
