Troubleshooting Face ID authentication problems on an iPhone 11 Pro, Face ID not working

Before you start ruling out software-related factors, make sure that nothing is covering your face. One of the requirements to use Face ID is to ensure that your nose, eyes and mouth must be fully visible or captured by the TrueDepth camera of your phone. That said, wearing of sunglasses that could block the infrared light used by the TrueDepth camera is not recommended. While Face ID works with many other sunglasses, try not putting them on while troubleshooting Face ID problems on your iPhone 11 Pro. Another requirement is to ensure that you are facing the TrueDepth camera, just like when you take a selfie or make a FaceTime call. Your iPhone must be an arm’s length or closer from your face.

If you’ve met all the said requisites but still couldn’t get Face ID to work as intended, try the following procedures to rule out software-related impediments.

 

First solution: Reboot your iPhone 11 Pro (soft reset).

Symptoms that are suddenly occurring are usually triggered by minor firmware issues including rogue apps and software glitches. To deal with these random symptoms, rebooting the phone is recommended. This is by far, the simplest yet very effective solutions to various types of system errors including Face ID authentication failure. Just follow these steps to soft reset or reboot your iPhone 11 Pro Max:

  1. Press and hold both the Side and Volume Up buttons for a few seconds.
  2. Release both buttons when the Slide to Power off bar appears.
  3. Swipe or drag the bar to turn your device off.
  4. After about 30 seconds, press and hold the Side button and then release when the Apple logo appears.

Wait for your phone to finish rebooting and then try using Face ID again to see if it is already working.

  3. Make sure that the Face ID & Passcode switch is turned on. Otherwise, toggle to turn the feature ON.

If the Face ID switch is already turned on upon checking, toggle it to turn the feature OFF and then back on again. This should give a quick refresh to your phone’s Face ID authentication system.

 

Third solution: Install new iOS update for your iPhone 11 Pro to fix Face ID that’s not working.

Software updates released by Apple are usually intended to fix widespread issues inflicted by stubborn system bugs. The latest version rolled out by Apple a few days ago is iOS 13.2.

Other factors you should eliminate are incorrect settings or invalid system configuration on your device. These settings can likewise cause conflicts to the Face ID authentication system directly or indirectly. As a result, Face ID stops working as it should.

All system settings and personal preferences will be removed afterwards. When the reset is finished, your iPhone reboots by itself and then loads up the default system values and options. To use necessary features, particularly those that are disabled by default, you will need to re-enable them individually. And that also applies to your phone’s Face ID feature.

 

Last resort: Erase your iPhone and set everything up as new. 

Performing a factory reset or master reset can be deemed among the last options if none of the previous methods is able to fix the problem. This will erase everything from your iPhone system including complex system errors that might have ruined the Face ID authentication system on your device. But before you proceed, be sure to back up all critical data saved on your iPhone storage as they will likewise be deleted in the process. You can back up your iPhone data to iCloud or iTunes in a computer. Once you have secured your backup file, you may begin erasing your iPhone 11 Pro using these steps:

  1. From the Home screen, tap on Settings.
  2. Select General.
  3. Scroll down and tap on Reset.
  4. Tap Erase all content and settings from the given options.
  5. Enter your passcode if prompted to continue.
  6. Confirm action by tapping the option to erase and reset your iPhone.

You can also use iTunes to manually erase and restore factory default settings on your iPhone through a computer. This would be a better option if you prefer to back up your iPhone data straight to your computer via iTunes.
