So I selfhost Vaultwarden which allows TOTP but I like to keep my 2FA and Password Manager separate, so I’m looking for something like Vaultwarden which can sync up with my server, but for 2FA only. I came across 2FAuth which can do it, but it only has webapp, so if a Alternative Service where there is a client for iOS and Android it would be a lifesaver. Thanks in advance for any suggestions or recommendations.
Frankly, if they aren’t tech savvy, you should just have them use Authy. No, it’s not open source, but it’s just fine for the average user.
