may be worth mentioning that privacy respecting browsers (librewolf) currently don't recommend FIDO2 passwordless authentication (doesn't work out of the box) and don't use CTAP2 protocol. When trying to set it up it won't work and won't use PIN (CTAP1).
Microsoft requires you to download their proprietary 2FA app to setup FIDO2 - please let's use another web app as an example.
