Module platform_passkey 

Passkey and WebAuthn host capabilities.

Passkeys are credential assertions, not raw biometric access. A browser, operating system, password manager, or hardware authenticator may use a fingerprint, face check, device PIN, or security key touch to unlock the credential, but the app receives WebAuthn-style registration or authentication data for server verification.
