Apple gave iOS security a boost today with the release of its 16.3 software update. For the first time, iOS users can use physical security keys for two-factor authentication (2FA) for their Apple ID. This new measure Announced by the company last year, adds a layer of protection for those facing unusual security threats, people like celebrities, journalists and government employees.
Physical key support should help prevent phishing scams, which can trick users into allowing an attacker access via 2FA. Using a device like the YubiKey means that only those with access to the physical key can log into your account. Although some security keys connect to the iPhone’s Lightning port, most use USB. However, the NFC and Bluetooth keys should work with the iPhone, and you can connect a USB to Apple’s Lightning to USB 3 Camera Adapter.
iOS 16.3 also includes updates to the Emergency SOS controls. You’ll still be able to call emergency services by holding down the power and volume up buttons, but now, it won’t call 911 until you let go. This allows you to cancel before emergency services are notified.
The update also adds bug fixes for issues like strokes not appearing on shared boards in the Freeform app, horizontal lines appearing on the iPhone 14 Pro Max after waking up, and a bug that prevented the home screen widget from Start lock will display the status of the Start application. Finally, it adds support for the new 2nd generation HomePod.
If you have a compatible device, you can install the update by going to Settings > General > Software update.
