Before you start, with a Face ID disabled, you will need a passcode to access your phone. We recommend you make sure your passcode is as strong as possible. Consider using a longer numeric or even alphanumeric code.
Temporarily disable Face ID
This can help you to prevent Face ID from unlocking your iPhone.
-
Press and hold the side button and either volume button for 2 seconds.
-
Once the sliders appear on the screen, press the side button to lock your iPhone immediately. If you don’t touch the screen for a minute or so, the device locks automatically.
Next time you unlock iPhone with entering your passcode, Face ID will be enabled again.
Turn off Face ID for good
-
Go to Settings > Face ID & Passcode.
-
Do one of the following:
-
Turn off Face ID for specific items: You can turn off different options: iPhone Unlock, Apple Pay, iTunes & App Store, or Safari AutoFill.
-
Turn off Face ID: Tap Reset Face ID.
-
Hopefully, now you can configure your Face ID accordingly.
