some fido2/webauthn keys can have a pin, and the client can request
a mode for the user verification.
'default' (no value set), lets the browser/device decide if the user has to
enter the pin of the device
'discouraged' requests that the user should not need to enter the pin
'preferred' requests that the user should need to enter the pin (if possible)
since we use webauthn only as a 2nd factor, having the user enter
the device pin on login may seem too much hassle for some users, so
give them the option
since this is a client option anyway, do not save it in the backend, but
in the browser local storage
