totp-generator VS totp

Someday this will come back to bite you, but you can store the secret key in your CRM, then use something like https://github.com/jaden/totp-generator to generate OTP codes.

I'm even one degree more extreme with my email 2FA though. I memorized the 2FA secret and put a TOTP generator project from github on a public subdomain on my web server. Together with the username and the password, which I also memorized, I am able to use any two devices (or any single device if I trust that it is not compromised) to gain access to my 2FA-protected email account.

I think the https://github.com/jaden/totp-generator you posted may be the better choice, it is far more self contained.

Hello, if I self-host Bitwarden's server, Can I user TOTP, because in the mean time, I can only enter TOTP code through web extension but can't use it ! Although it is easy to implement a free TOTP generator ! If self-hosting bitwarden is not enough to unlock this functionality, is there another way to do this like adding my own totp generator or by linking vault with passman ?

here's a command line one https://github.com/arcanericky/totp

TOTP never requires a phone number. On GitHub, they either show you a qr code you can scan in an app, or a text you can import. All apps support this sign up process, from google authenticator to console-based tools like totp[0].

Other 2FA may require phone numbers.

I rolled my own by wrapping a UI around this awesome little go utility... https://github.com/arcanericky/totp
