Apple's Face ID was originally designed to facilitate users to unlock, but because of the need to wear a mask when going out, Face ID is often unusable and requires a password to unlock. Now, Apple's new version of iOS, iOS 15.4, will support wearing a mask to use Face ID, and in the developer beta version of Apple's latest iOS 15.4, users can choose "Wear a mask to use Face ID" or "Don't use Face ID when wearing a mask".

Can all iPhone users use it? Does this reduce unlock security? Can I unlock them with glasses? With the advent of new features, these problems have also become the doubts of users.
First of all, wearing a mask to use Face ID is only open to iPhone 12 and 13 users for the time being, at the same time, wearing a mask to unlock still supports wearing glasses, but can not wear sunglasses.
