FIDO2 for ASP.NET supports the FIDO Authenticator Metadata Service (MDS). This allows a FIDO relying party to load metadata about certified FIDO authenticators to aid in authenticator validation and authorization rules.
To use the FIDO MDS, you will need to get an access token by registering with the FIDO Alliance.
You can then enable support for the MDS by using the AddFidoMetadataService
registration.
services.AddFido(options =>
{
options.Licensee = "";
options.LicenseKey = "";
}).AddInMemoryKeyStore()
.AddFidoMetadataService(options => options.AccessToken = "");
