Passkeys (Passkey Authentication)

A FIDO credential that is backed up (usually to the user’s platform account; e.g., Google Account or AppleID), allowing users to restore the credential to, and use it from, another device. From a user experience standpoint, this will be very similar to how one interacts with a password manager today to help them securely enroll and sign into websites – only it will be far more secure. For service providers, this expands the range of options for deploying modern, phishing-resistant authentication.
