If you need help using Face ID to unlock your iPhone or iPad, authenticate purchases, sign in to apps or if you're asked to enter your passcode, find out what to do.

To check your Face ID settings, go to Settings, then tap Face ID & Passcode. Make sure that Face ID is set up and that the features you're trying to use Face ID with are turned on.

Remove anything that might be covering the TrueDepth camera like dirt, a case, or a screen protector.

If you're using an iPad in landscape orientation, make sure that your finger or palm isn't covering the TrueDepth camera. If it is, an alert might appear at the top of the screen that says "Camera covered" with an arrow pointing at the TrueDepth camera.
