FIDO metadata

You can use the FIDO Metadata service to implement the TrustAnchorProvider interface to provide information about authenticators. You can integrate FIDO metadata into the SDK, but you can also always use your own source of trust anchors.

You can choose how to integrate the data into the SDK (via external service, module, or imported as a file). Regardless of the method, metadata should be integrated via the MetadataProvider interface, which provides the necessary information based on the authenticator AAGUID. The data can be fetched from https://mds.fidoalliance.org in the JWS format.
