Coming back to iOS 15.4, we find that the long-awaited feature to use Face ID while wearing a mask has finally arrived. If this feature is enabled, Apple’s facial recognition technology can recognize your face even if you have a mask on. However, Apple warned that enabling this new feature could make Face ID less accurate overall. To enable this feature, go to Face ID & Passcode to find a new toggle for using Face ID with a mask on, and turn it on.
