Apple Releases iOS/iPadOS 16.3 With Security Keys for Apple ID and More

The headlining feature of the update is the support for Security Keys for an Apple ID.

First announced in November, that allows you to strengthen the security of your Apple ID by requiring a physical security key as part of the two-factor authentication process on new devices.

Here are the complete release notes:

This update includes the following enhancements and bug fixes:

New Unity wallpaper honors Black history and culture in celebration of Black History Month
Security Keys for Apple ID allow users to strengthen the security of their account by requiring a physical security key as part of the two factor authentication sign in process on new devices

Apple Watch users can now also download watchOS 9.3

The watchOS 9.3 update can be downloaded now through the companion Watch app on your iPhone by heading to General > Software Update in the My Watch portion of the app. You can also go to Settings > General > Software Update on an Apple Watch.

Your watch needs to have more than 50 percent power and connected to a charger. Like most Apple Watch updates, it could take anywhere from 30 minutes to an hour to complete, so be patient.

It’s compatible with the Apple Watch Series 4 and later.

Along with the pictured Unity Mosaic watch face, the update offers bug fixes and other smaller improvements.
