My face id error but I don’t want to see notifications it.how to do?

Hi roth256,

We're happy to provide some assistance.

We recommend the troubleshooting steps via the link below since Face ID has been disabled on your device.

If an alert says Face ID has been disabled on your iPhone or iPad Pro

To perform the troubleshooting actions recommended by the article above, please read through and complete the steps in the section titled "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.

We're recommending the steps above because they directly address the issue you initially reached out to the community about, which is that Face ID has become disabled on your device.

We hope this helps.

Thanks for using the Apple Support Communities.

Cheers!
