Apple Releases iOS 16.3 With Security Keys for Apple ID, New HomePod Support, Bug Fixes and More

Apple today released iOS 16.3, the third major update to the iOS 16 operating system that first came out in September. iOS 16.3 comes over a month after the launch of iOS 16.2, an update that added the Freeform app, Apple Music Sing, Advanced Data Protection, and more.

‌iOS 16‌‌.3 can be downloaded on eligible iPhones and iPads over-the-air by going to Settings > General > Software Update. It can take a few minutes for the updates to propagate to all users due to high demand. Apple has also released iOS 15.7.3 for iPhone users who have older devices, with the update offering security improvements.

Today's update introduces Security Keys for Apple ID, allowing for physical two-factor authentication that replaces the digital two-factor authentication used for ‌Apple ID‌ logins. There is a new Unity wallpaper, along with support for the second-generation HomePod.

Apple tweaked Emergency SOS to prevent accidental emergency calls. You can still activate Emergency SOS when holding down the side button with the up or down volume button, but a call won't be placed until the buttons are released.

A number of bug fixes are also included, with Apple addressing an issue that could cause horizontal lines to temporarily appear on the iPhone 14 Pro Max, a bug that could result in the Home Lock Screen widget not accurately displaying Home app status, and Siri bugs related to music requests and CarPlay. Apple's full release notes for the update are below:
