Apple has released iOS 16.3, which adds the ability to use a security key to lock down your Apple ID and appears to bring the company’s Advanced Data Protection for iCloud feature to countries outside of the US. It also tweaks the Emergency SOS call system, includes a new “Unity” wallpaper, and adds support for the second-gen HomePod.

Last year, Apple announced the hardware key feature, which lets you use something like a Yubikey as a second factor to log in to your Apple account, as part of a push to help people lock down their iCloud accounts. Also included in that announcement was Advanced Data Protection, which expands the types of data that are end-to-end-encrypted in your cloud storage. The feature came to the US with iOS 16.2, but the update released on Monday seems to make it available globally — Apple has removed a note from a support document saying that it’s only available in the US, and we’ve seen at least one report from someone in another country saying it’s available.

We also anticipate that iOS 16.3 will support some nice new features for HomePod Mini owners after those devices get a new software update as well. The most notable change is that the smart speakers will act as temperature and humidity sensors, which you can use in automations. The update may also let you set up automations using your voice and ask Siri where family, friends, and Find My devices are.

You can read about a few other upcoming HomePod features and our impressions of them here, and we’ll keep you updated about whether this update actually enables them.

We’re also keeping an eye out for a macOS update that will bring support for Apple ID security keys to desktops and laptops.

You can download the update by going to Settings > General > Software Update. It can take a while before it shows up for everyone, so you may have to check back every few hours.
