The FIDO metadata, by and large, only contains hardware authenticators (these are the only ones you can verify their attestation statement). The metadata comprises information we use in the UI to show the user. For software authenticators, we, therefore, have nothing to show. suggested using the passkey project to add that information (for now, they have a list of common software authenticators). The project may not be stable, but I’ll look into using this to improve the UI.
