Storing 2FA codes is just the beginning. Bitwarden aims to add defense in depth to authentication.
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.
Is that a thing? Usually those have a fallback to a regular TOTP code.
I use Okta for work because we integrate SSO with it everywhere, but I could technically enter a code every time and swap out the Okta app for the other TOTP app I use.
My company is a MS shop, but they use TOTP as the second factor, and even that is optional. My department uses Okta, which is a completely separate system (we're a weird, separate unit entirely from most of the rest of the company).
They must now require HOTP or something now. TOTP doesn't care what machine it's on, whereas HOTP does (well, you could spoof it if you really wanted).
They're probably using HOTP or something else, not TOTP. TOTP is literally just the key + any clock. Or maybe it's the "click button to authenticate" and not the "enter code to authenticate," which might not be HOTP or TOTP, but something else entirely (e.g. Steam's system is neither AFAIK).
If it's TOTP, you just need to get the key and can use any authenticator app.
4-5 TOTP apps? So far, when, e.g. Microsoft or Google have insisted use of their own Authenticator app is required, it’s worked fine for me using Ente Auth or similar just by entering the code / QR.
Yup, most 2FA is just TOTP, which is a pretty simple, open standard and is hardware independent. All you need is a key (the QR code or the numbers) and access to a reliable time source and you can make a TOTP app on anything.
I use Aegis on my phone and Authenticator on Linux (some GTK app), and they both produce identical codes for the same key.
This even works with some apps that hide the standard part - like Symantec VIP - it’s possible to extract what they are doing and use a standard TOTP app instead of VIP.
