How to Enable Face ID on iPhone is straightforward once you use the current iPhone controls. The exact wording can vary slightly by iOS version, carrier, and iPhone model.
- Open Settings > Face ID & Passcode.
- Enter your device passcode.
- Tap Set Up Face ID.
- Position your face in the frame and slowly move your head to complete the scans.
- Choose which features can use Face ID.
Before making the change, make sure the iPhone is running a current iOS release and that you know any passcode, Apple Account, carrier, or app credentials the feature may require. If the labels on your screen do not exactly match these steps, use Settings search to find the named feature rather than choosing a similarly named control. Apple occasionally moves settings between iOS releases.
