Configure FIDO2 security key restrictions

In this post I’ll provide a short introduction about the FIDO2 security key AAGUID (and how to find it), followed by the steps to configure the FIDO2 security key restrictions. I’ll end this post by looking at the end-user experience.

An AAGUID is a 128-bit identifier that indicates the …
