# Face ID Authentication

* Condition: passcode is enabled, and the app allowed biometric authentication.
* To access the function, please follow the steps below.

**Step 1**

* A Glance at the screen of the user's device, and Face ID will detect the face.                                                                                                                                                                        ![](/files/bqBGj87nTKHewRz0KFy8)

**Step 2**

* If the face is recognized --> Authenticate successfully. Users can access the app.                                                                                                                                                       ![](/files/C4wYB3FNnKdGUWpsafah)
* If the face is not recognized, let's try again.                                                                                                                                             ![](/files/r8W5NpD0KfyXvFF7Ddgr)
* If the face is not recognized many times, depending on the device, the user must enter the passcode to authenticate.                                                                                                                                                                                                           ![](/files/o756T4XxOJ6lcpt4dmFC)
