Face ID is an excellent addition to the iPhone and iPad, and it still feels like magic every time it works. But just like Touch ID before that, you may need to prevent apps from using it. Here's how.
If you have allowed a third party app to use Face ID as its authentication mechanism, it may be good to make it easier and faster to log in to everything from your bank app to your shopping list. However, there may be times when you want to revoke that condition. Whatever the reason for your decision, which prevents an app from using Face ID, requires only a few cranes.
Recall access through face ID and password Settings
To get started, open the Settings app and then press "Face ID &"
After you has entered your password to access, press "Other apps".
Here you will see a list of all apps that have requested access to Face ID, as well as its current state. The shift to the right of the app's name indicates whether or not the app currently has face ID access. Change any apps you want to revoke access to.
Recall access via the app's settings
Another method of achieving the same result is to open the setup app again, scroll down until you find the name of the app you want to recall the face ID, and then press it.
Here you will find all the app's permissions. To remove face ID access, switch the switch to the "off" position.
