Since I added my backup Yubikey to #Github yesterday I went to revoke the "Authentication App" option (i.e. TOTP) as a #2FA method, but it looks like maybe there's no way to revoke the "Authentication App" as an authentication method once you've set it up?
I see this on a number of sites, where they offer lots of different #authentication methods and encourage you to have multiple so you won't get locked out. For #security , though, I think it's just as important to be able to revoke weaker methods when you setup stronger ones, but this seems to frequently be neglected, which looks like a sort of half-hearted attempt at security to me.
This wouldn't be surprising to me in general, but I guess I expected Github to meet a higher standard, given how many processes on the Internet expect to be able to trust the contents of specific Github repositories. Maybe I'm missing something in the UI?
