IPhone owners who migrated from Touch ID to Face ID may have complained, until the launch of iOS 12, of the possibility of registering only one face as a form of biometric authentication of the iPhone X. This is because, unlike the latest technology, Touch ID allows to register up to five fingerprints.
On the one hand, it makes perfect sense: we have ten fingers, but only one face. However, given some Face ID recognition failures, Apple decided to implement a feature called “alternative look” in iOS 12 which, in turn, allows you to register a second face on compatible iPhones.
Although the purpose of this option is to record your appearance with accessories and other accessories (such as glasses, lenses and / or hats), it is possible to use it to register another person’s face in order to give access to your device without having to enter the password. The procedure is basically the same as that performed during the initial Face ID setup.
To add a second face, make sure your iPhone is updated to the latest version of iOS (Settings »General» Software Update) and follow the steps below:
- Open the Settings app and select “Face ID and Code”. Enter the access code, if requested.
- Tap on “Configure an Alternative Look”.
- Tap “Continue” and register your alternate look or someone else’s face as normal.
Remember that if you want to add another person and later decide to remove them, you will need to reset your Face ID (which will remove both registered users). In addition, the feature does not allow you to record a face horizontally (the iPhone must necessarily be standing).
