    Whenever we use third-party apps on the iPhone, they often require distinct permissions. These apps could be related to banking, messaging, or social interactions. Enabling Face ID for these apps can spare you the need to repeatedly enter your iPhone passcode.

    Here's how you can grant permission for a third-party app supported by the iPhone:

    • 1Go to Settings> Face ID and Passcode> Other apps.
    • 2Tap that particular app you want Face ID on.
    • 3Enable the toggle of Face ID on the app.
    check face id permission

    3. Clean the face ID Sensor

    As time passes, the camera might accumulate dirt or oils. You'd better employ a gentle, dry cloth to carefully cleanse the sensor array located at the top, ensuring no obstruction remains. Keep in mind that certain robust cases and thick screen protectors could partially cover the sensors, potentially causing Face ID disruptions. It's worth contemplating their removal in such cases.

    4. Avoid Blocking Your Face

    For Face ID to perform smoothly, camera needs a clear view of your eyes, nose and mouth, so avoid covering this area with a mask or similar clothing. If you've configured Face ID while wearing a mask, make certain that your eyes remain visible to the camera when utilizing the feature.

    6. Update your iPhone to iOS 17

    Apple frequently releases updates for iOS and iPadOS to address bugs, fix vulnerabilities, and enhance their software. If you're facing Face ID issues, the root cause might be in the underlying software.

    In such instances, consider updating your iPhone to the most recent iOS version. To do so, navigate to Settings > General > Software Update. If you've already upgraded to iOS 17, ensure that your iPhone is running the official iOS 17 release, not an iOS 17 beta version
