Nov Matake gave a keynote presentation at FIDCon about the next stage of WebAuthn and Passkeys on Apple platforms. He demonstrated syncing Passkeys across devices and using them for autofill on websites. Some challenges remain around credential changes and re-authentication. Syncing Passkeys across different operating systems like Windows, Android, and ChromeOS will also need to be addressed to make the experience better for users.
