All you have to do is visit the Settings menu and select Biometrics and Security from the drop-down menu. There is a feature called face lock that you can use. You can use Face ID on all iPhones up to and including the iPhone X, which includes the base iPhone 11, 12, and 13, as well as the iPhone Pro, Pro Max, and Mini models.

To enable Face ID lock on your iOS device, navigate to Settings > Face ID & Passcode.
