ID-Austria is the Austrian government identity provider offering Webauthn and hardware tokens, see compatible devices. Site lists “Token, die FIDO2 Level 2 zertifiziert mit WebAuthn unterstützen”
When registering with my Nitrokey 3A NFC I get:
"A-Trust wants to see the make and the model of the ..."
Fehler: Dieser FIDO-Sicherheitsschlüssel konnte nicht verifiziert werden.
SessionId: A4_RXOX.................
Is the Nitrokey 3A NFC not FIDO2 Level 2 certified with WebAuthn? If it is, will you get in contact with A-Trust to enable your Nitrokey 3A FIDO2 keys?
My Nitrokey verified correctly:
user@debian:~$ .venv/bin/nitropy fido2 verify
Command line tool to interact with Nitrokey devices 0.4.38

I see sometimes problems with other websites if one rejects all cookies or only accepts some of them. For registration one can accept more cookies and for login from my experience one can just accept minimal cookies.
According to ID-Austria the FIDO Alliance page https://fidoalliance.org/certification/fido-certified-products/ does not list the Nitrokey 3A NFC. Only tokens listed there are allowed to be accepted by ID Austria. Seems the level 2 certification is missing for the Nitrokey.
According to the ID-Austria service provider a-trust there is no formal admission process, but as soon as the Nitrokey is listed with the required certifications by the FIDO Alliance, manufacturer Nitrokey could send a test token to a-trust and they will accept the key.
