Apple released iOS and iPadOS 16.3, macOS Ventura 13.2, and watchOS 9.3 today. The updates focus primarily on bug fixes and under-the-hood improvements, but there is one notable addition: Apple ID got support for hardware security keys. From a report: Once they’ve updated to the new software, a user can opt to make a device like a YubiKey a required part of the two-factor authentication process for their account. It’s unlikely most users will take advantage of this, of course, but for a select few, the extra security is welcome. Other additions in iOS 16.3 include support for the upcoming new HomePod model, a tweak to how Emergency SOS calls are made, and a new Black History Month wallpaper. On the Mac side, hardware security key support is joined by the rollout of Rapid Security Response, a means for urgent security updates to be delivered to Macs without issuing a major software update. The watchOS update is oriented around bug fixes.
