Face ID doesn’t work

Hello dipen69,

If you're seeing an alert that Face ID has been disabled, you'll want to follow the steps under "What to do next" here: If an alert says Face ID has been disabled on your iPhone or iPad Pro - Apple Support

What to do next

1. Update your iPhone or iPad to the latest version of iOS or iPadOS.

2. Check if there is an issue with Face ID in your iPhone's parts and service history. To do this, open the Settings app, tap General, then tap About.

3. If you still can't enroll your face or unlock your device with Face ID, you can take your device to an Apple Store or Apple Authorized Service Provider, or contact Apple Support about your iPhone or your iPad.

Only a trained technician should service your device. Improper repair, modification, or use of nongenuine Apple components in the laser systems might prevent the safety mechanisms from functioning properly and could cause hazardous exposure and injury to eyes or skin

If instead Face ID isn't working to unlock your phone or some other issue, these steps should help: If Face ID isn't working on your iPhone or iPad Pro - Apple Support

Thanks for participating in Apple Support Communities.

Take care!
