Dumb question … why can’t FaceID on my iPhone be used for 2fa/webauthn/fido2? Or is that “PassKeys”?

  On iPhones and TouchID capable devices this has been available for quite some time now. I don't know how much work setting this stuff up is, but AFAIK FIDO2 is already available on-device. Using an external device for FIDO2 authentication is something I can't add much about. The FIDO2 standard should allow for this and Apple and Google are working to make such a mechanism available if I recall, they made a whole PR thing out of their FIDO2 support a month or two ago. There are apps that can do this as well though I don't know any specific ones for the Apple side of things.
