Passkey support

[j5155]

Is your feature request related to a problem? Please describe.
I like having multiple factors of authentication but getting out the codes can be annoying.

Describe the solution you'd like
I have a Yubikey and would really like to be able to use it to login through passkeys. This would also allow people to use passkeys integrated into devices such as phones.

Describe alternatives you've considered

Additional context

We will see how hard this is once I get my YubiKey.

As a note, none of those libs will work since this is a web app. So.. there is no USB access.
