Hey!

I basically want to replace the Google Authenticator app in style and functionality:

1. List all TOTP tokens and their validity time (with a name and order I decide).
2. Allow me to periodically or on change back up the whole thing to some off-site storage, keeping the last N backups.
3. Have a native app for Android or an actually good PWA.
4. Don’t do magic bullshit like fetching icons, hide tokens, etc.
5. Be actually secure (i.e. don’t roll your own auth)
6. Just be a TOTP manager, and nothing more! No, I’m not interested in a password manager, thank you. I also don’t want any other OTP methods I don’t use.
7. Don’t be a one-man projects where the availability is not clear in >1 year.

Any experience is welcomed. Thank you!
