Apple today released iOS 15.4 and iPadOS 15.4, which is the fourth major update to the iOS 15 and iPadOS 15 operating systems first released in September. iOS and iPadOS 15.4 are huge updates that bring quite a number of useful new features to iPhone and iPad.

Face ID with mask

With iOS 15.4, there is now an option to unlock your iPhone while wearing a mask without the need for additional hardware such as the Apple Watch. Apple warns that Full Face ID is the most secure option, but a Face ID mask is now available.

Face ID can be enabled with the mask after updating to iOS 15.4, and is designed to use the area around your eyes for authentication purposes. It works with glasses, but is not compatible with sunglasses, and you have to look at the iPhone‌ to unlock it with a mask.

Face ID with a mask is limited to the iPhone 12 and iPhone 13 models, so it’s not available on the iPhone 11.

Apple in iOS 15.4 adds AirTag anti-stalking changes announced in February. When you set up AirTag or Find My Accessory, there is now a warning that the device is locked with an Apple ID and that using it to track someone without their consent is a crime.

Apple ID warning

“You can locate this item using the Find My network,” the setup screen reads. “Using this item to track people without their consent is a crime in many areas around the world. This item is designed to be detected by victims and to enable law enforcement to request owner identification information.”

With this warning, Apple wants to make it clear to those who may be using AirTags and Find My compatible devices from third-party companies as prosecution tools that this use case is illegal and has criminal ramifications.

Apple is also fixing a bug that was causing confusion about unwanted tracking. AirPods can cause an “unknown accessory alert” warning that some people interpret as a notification from an AirTag. AirTags cannot display “Unknown accessory detected” messages, which are caused by AirPods Pro, AirPods Max and AirPods 3rd generation, and in some cases, “Found Network Accessory”.
