Why did my Face ID stop working all of a sudden?
My phone stop showing the Face ID option out of no where. And now I cannot use it for anything.
iPhone XR, iOS 16
Hello,
Apple has several documents helping you with Face ID.
This document is specific to seeing a 'disabled' Face ID alert, and explains what to do when you see that notice. --> 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 general 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.
If an app or feature on your device is not working, not appearing*, or is restricted (grayed out), it may have been disabled using Screen Time, or by an IT administrator if you are using a device owned by an employer or educational institution.
- Read this document about using Screen Time on an iPhone, iPad, or iPod touch --> Use Screen Time on your iPhone, iPad, or iPod touch - Apple Support
Tap Settings > Screen Time > Content & Privacy > scroll to Allow Changes.
- If the device is managed (Settings > General > VPN & Device Management), contact the IT department that is doing the managing.
