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).
Authy is great, but I really wanna selfhost 2FA, as I did personally ran into issue back in 2019 or 2020 where Microsoft Authenticator suddenly lost 2FA cloud sync backup so I had to send my Legal ID proof for multiple accounts for them to disable 2FA, while I still didn’t recover my old Instagram account as face verification kept on failing and Meta’s human support is nonexistent, and this happened for multiple users on Microsoft Authenticator and was showered with negative reviews on play store back then. Since then I dont trust Cloud Sync for any thing, so I did use Aegis and did auto backups and sync on that,but currently I’m looking for something simple for my parents which can Autosync without them worrying about restoring backups, where they can just login and use.

There is also a authy-export tool that makes it pretty easy to export all the tokens to selfhosted
passrepo.
