Apple has released iOS 16.3, bringing support for the newly-announced HomePod and physical security keys used for two-factor authentication.
Following a beta period that started on December 14, the update for iOS 16.3 is now downloadable to iPhone. It doesn’t appear to have many user-facing updates, though it ensures compatibility with the new HomePod and its features.
The update includes support for hardware security keys, such as those from Yubico, that can be used for two-factor authentication for an Apple ID. Those with a notable public presence will benefit from the feature, such as journalists, celebrities, and politicians.
