2FA with Yubico Authenticator
I use Yubico Authenticator, it works the same as Google Auth, but I noticed that I can use only one Yubikey, an improvement would be to allow multiple keys.
it would a awesome idea, I would like to use 2fa, but I cant for many reasons.

I own a physical security token and I'd really like to have other 2FA options other than TOTP, like U2F/FIDO2, WebAuthn, or Yubico OTP. It would make my and my fellow physical token owners' life much easier, while keeping the same account security.
