Q:"How to add a new Face ID on my iPhone 11? I want to share my device with my girlfriend." - from iPhone Forum

Face ID, a facial recognition system developed by Apple, is first introduced to iPhone X in 2017. Since then, the follow-up iPhones including iPhone X/XR/XS/XS Max/11/11 Pro/11 Pro Max and even iPad Pro (3rd generation) are designed with safer and faster Face ID as the unlocking system instead of Touch ID.

For this new feature, many users have a query that they wonder if Apple allows a second Face ID to be added for sharing the device with trusted friends. On this question, the following gives detailed reply and explains how to do it on the iPhone.

Part 1. Something Worthy of Attention about Face ID

Below are some facts about Face ID. Get to know them before acting, twice as much can be accomplished with half the effort.

1. Face ID is designed to replace Touch ID as the unlocking system on iPhone X and later. Besides unlocking a device by biometric authentication, it also allows making payment, accessing data, and more. Note that it is only applicable to all new iPhone models. For iPhone 8 and former, not Face ID but Touch ID can be enabled.

2. Unlike Touch ID allowing users to add five different fingerprints for authentication, Face ID feature only allows adding two different appearances on the same iPhone. When you would like to add a second Face ID on your iPhone, the general recommendation is to set your face as the main Face ID and then set another face as an alternative Face ID.

3. Does wearing glasses affect facial recognition? Do users need to add a face with glasses as a second Face ID? It is totally uncalled-for. With powerful biological recognition techniques, the system will record changes of your face every time when you fail to unlock your device with Face ID. It will learn how your face change for a successful recognition of your face next time.
