Since this github 2fa thing is happening, I'm gonna need a better solution for 2fa. So far I've used Authy on my phone for work stuff. That's fine. But for personal stuff, I want more control.

What good open-source options do you all prefer to deal with TOTP? I'm thinking I'll use Bitwarden to sync TOTP keys, since I already use them for passwords, which means I need apps which let me freely and easily copy those secrets around. I use Linux, iOS and macOS, so I'll need apps for all those platforms.

I'm not interested in moving to a different password manager, and I'm even less interested in moving to a closed source password manager. (Imagine that, handing all your passwords to some closed source application from some random US company in the name of security...)
