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
Then how do you secure the backup without 2FA?
Or is it 2FA all the way down?
You could store it on an external drive. You can encrypt it with VeraCrypt as well.
Aegis encrypts it with a password, then you copy it somewhere. It’s just a set of keys and you can have as many copies as you want (I have three, one phone and two desktops).
Aegis doesn’t run on your desktop using the same key, it’s just a key stored there, right?
No, I use a different authenticator app (called Authenticator in the Flatpak store), but it does use the same keys. So I import the keys from an Aegis dump so I can generate exactly the same keys on my desktop app that I do on my phone.
TOTP is a really simple system, as long as I have access to the secret key and a reliable time source, I can generate the exact same tokens as any TOTP app would.
