Check Your Face ID Settings
If you can’t use Face ID to do things like using Apple Pay or autofill your passwords, it’s possible that your Face ID settings aren’t allowing it. Here’s how you can change the settings.
- Open the Settings app on your iPhone or iPad.
- Scroll down and tap on Face ID & Passcode.
- Enter your passcode.
Once in, you can change your Face ID to work for unlocking your iPhone, using Apple Pay, and other apps that you can lock with Face ID.
