Today, Google started rolling out an update to its iOS apps and online services that adds support for WebAuthn-capable security keys.
Hardware security keys are devices that generate unique cryptographic keys that are used as a second proof during an authentication process after users have successfully entered their username and password.
Security keys can be linked to the device where the login operation takes place via Bluetooth, USB, or Lightning connections.
iOS devices have supported security keys since their early beginnings, and users have been able to pair security keys with their iPhones to secure accounts with both a password and a cryptographic signature generated on the security key.
