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.
For people who don’t mind it not being self hosted: Authy is good for this. You can also set a backup password (to encrypt your tokens on their servers) and optionally use it cross device.
You can allow multi device temporarily to setup, then disable to not allow new devices, etc.
(I get you didn’t ask this specifically, but figure it could be useful to someone else).
There is also a authy-export tool that makes it pretty easy to export all the tokens to selfhosted
