Apple has released its latest software update, iOS 16.3, with a focus on enhancing security measures for users. For the first time, iOS users can now use physical security keys for two-factor authentication (2FA) of their Apple ID. This new measure, which was announced by the company last year, adds an additional layer of protection for those facing unusual security threats, such as celebrities, journalists, and government employees.
Physical key support is designed to help prevent phishing scams, which can trick users into allowing an intruder access through 2FA. Using a device like the YubiKey ensures that only those with access to the physical key can gain access to the user’s account. While some security keys plug into the iPhone’s Lightning port, most use USB. However, NFC and Bluetooth keys should also work with the iPhone, and users can plug in a USB key using Apple’s Lightning to USB 3 Camera Adapter.
In addition to physical key support, iOS 16.3 also includes updates to Emergency SOS controls. Users will still be able to call emergency services by holding down the power and volume-up buttons, but the update now allows users to cancel the call before emergency services are notified.
The update also includes bug fixes for issues such as strokes not appearing on shared boards in the Freeform app, horizontal lines appearing on the iPhone 14 Pro Max after waking, and a bug that prevented the Home lock screen widget from showing the Home app’s status. Additionally, the update adds support for the new second-generation HomePod.
Users with compatible devices can install the update by heading to Settings > General > Software Update.
