iOS 16.3 beta includes support for physical security keys

Use security keys as a second factor for sign-in

It will be possible to sign into an Apple ID using a physical security key as a second factor starting in iOS 16.3.

By requiring a hardware security key, users would need something like a Yubikey to log into their devices or Apple's websites. Security keys can interface over USB, Lightning, or NFC — meaning the device has to be physically present for the user to login.

Apple says that the feature will be useful for people with a public profile, like celebrities, journalists, and members of government. The physical security key replaces one of the two factors for authentication and eliminates attack vectors that involve phishing.
