Uhh are you assuming MFA is... somehow a bad thing?
No, but it does present more data for the unscrupulous.
Aside from SMS/email, which should be avoided anyway for other reasons, or proprietary solutions like MS’ or Steams approach, there is nothing to be gained from TOTP or WebAuthN.
TOTP (the 6 digit code that changed every 30 seconds, usually) is just a hash of a shared secret between you and the server, and the current time rounded to the nearest 30 seconds.
WebAuthN/FIDO2/U2F is private by design. Keys/authenticators derive a unique key for every credential pair, you can even register the same key multiple times because of this. About the only thing you gain is knowing what type of authenticator is being used, which is of questionable value at best.
Thank you for this, I learned something today.
I wasn't rubbishing 2FA I was saying that in order to use it you usually need to use a mobile phone and it's the phone that I regard as being a security risk for any number of reasons.
Ah I see, and you’re most welcome. 2FA is something I am very passionate about, to the point I’m trying to convince my whole family to use security keys, but I come up against a lot of resistance to it
