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
I haven’t been entirely happy with Bitwarden for other reasons. You can’t self host and share with one other person without paying them $40/year. Their advertising is deceptive, because they say you can do both for free. But that one or the other, not both.
You also can’t easily share individual passkeys outside of the app. If you want to grab a passkey, you have to export your entire vault.*
It’s basically annoyance-ware.
* note that sharing passkeys is not best practice, but there are use cases.
I don’t think I realized that was a limitation because I’ve been using the Vaultwarden fork. https://github.com/dani-garcia/vaultwarden
As others have said vaultwarden is the solution here. It is free, you can manage multiple vaults, totp is free. All the platform bit warden apps & plugins work with it. Supposedly it is leaner and easier to set up. Don’t know for sure because it is all I have used.
For shared passwords, I have a family vault where I put my streaming pws and such and everyone has access without having to share my personal vault.
