In light of the considerable confusion surrounding passkeys registered for two-step login in Bitwarden, it would be very helpful to publicize a simple procedure for determining whether a registered key is a FIDO U2F key or a FIDO2 key.
For example, should a Yubikey passkey be assumed to be a U2F key, if it is not listed when executing the command ykman fido credentials list?
@kpiris — any thoughts on this?
