My face ID not working I need help please

Hello,

Apple has several documents helping you with Face ID.

This document explains what to do if you see a 'disabled' Face ID alert --> If an alert says Face ID has been disabled on your iPhone or iPad Pro - Apple Support

If you don't see a 'disabled' message but do have issues with Face ID not working properly, explore the list of things to try in this document: If Face ID isn't working on your iPhone or iPad Pro - Apple Support

If the first 8 don't solve the issue then use #9, contact Apple.
