If these options are disabled, you will need to enable them to use Face ID effectively. Additionally, ensure that you have registered your face properly.
If you find that Face ID settings look correct but it’s still not working, you may want to try re-registering your face. You can do this by tapping on “Reset Face ID” and then following the prompts to set it up again. Make sure to position your face within the frame during the setup process for better results. This step can often resolve minor glitches that may be affecting the functionality of Face ID.
