@canard164 The FIDO API currently supports WebAuthn Level 1. Passkeys seems to be marketing speech for WebAuthn Level 3 (or some specific features of it). Some of these features are surely on the roadmap (like using the phone's secure storage as a roaming authenticator for desktop devices).
As "Passkeys is not a formal term of FIDO Alliance or its specifications", figuring out which feature exactly will be relevant for someone that wants Passkeys support is not really possible.
