Face ID is one of the most convenient features on your iPhone, allowing you to securely unlock your device, make payments, and access sensitive information with just a glance. However, many iPhone users encounter issues with iPhone Face ID not working. This article will explain why Face ID is not working on iPhone and provide step-by-step instructions on how to fix it.

If you're wondering, "Why is my Face ID suddenly not working on my iPhone?" several factors could be at play. Some of the most common reasons why Face ID isn't working include:
Now that you know some of the reasons iPhone 17 Face ID is not working, let's go over the most effective solutions.
One of the first things you should check is whether Face ID is properly configured. You may have accidentally disabled Face ID, which is why it isn't working. Here are the steps:
Step 1. Go to "Settings" on your iPhone.
Step 2. Scroll down and tap "Face ID & Passcode".

Step 3. Enter your passcode to verify your identity.
Step 4. Make sure Face ID is enabled for unlocking your iPhone, Apple Pay, and other features.
The TrueDepth camera is located on the front of your iPhone or iPad. If it is blocked by dirt, a screen protector, or a case, Face ID will not work properly. Make sure to check the camera regularly and keep it clean. To do this, follow the steps below:
Step 1. Turn off your device and check the front camera area to ensure there is no dirt or obstruction.
Step 2. If you are using a case, make sure it is not covering the camera area.

Since Face ID works by detecting and identifying face patterns, it requires the face to be visible to work perfectly. When the Face ID is not working properly, check if anything is covering the most important parts of your face, like the nose, mouth, and eyes, which need to be scanned by the camera. By default, Face ID will not work if your face is covered with sunglasses or a face mask.
The Face ID will only work on your iPhone if you hold it in a portrait position. On an iPad, it will operate in landscape and portrait. So, depending on your device, ensure you hold it in the correct position. Ultimately, it is crucial to check the alignment before using the Face ID.
Face ID might not work properly on an iPhone in dark conditions or when the lighting is dull. The scanner can't read facial features accurately in these conditions, where there's no proper light. To resolve this, move to where there is proper lightning.
Check that the TrueDepth camera is in a range where it can correctly detect your facial features. Usually, the distance between your face and the TrueDepth camera should be 10-20 inches, which is about arm's length. It should be close to the face, like when answering a call on FaceTime or taking a selfie. This way, the camera will capture your facial features fully.
Is iPhone Face ID still not working after the update? It could be that your appearance changed, which led to recognition failure. You should create a new alternative appearance. It may help fix the issue at hand. To give it a shot, follow these steps:
Step 1. Head to "Settings" and tap "Face ID & Passcode". Enter the password of your iPhone to continue.
Step 2. Now, click on the "Set Up an Alternative Appearance" option.

Step 3. Follow the onscreen instructions to come up with a new appearance.
If none of the above methods work, you can try resetting Face ID and setting up your facial data again. Here is how to fix Face ID not working on iPhone:
Step 1. Open "Settings", go to "Face ID & Passcode", and tap "Reset Face ID".
Step 2. Tap "Set Up Face ID" to register your face again.

Temporary system glitches can cause Face ID to stop working properly. In such cases, a simple restart can resolve the issue. To restart the iPhone, follow these steps:
Step 1. Press and hold the "Side" button and either "Volume" button until the power-off slider appears.
Step 2. Drag the slider to turn off your iPhone.
Step 3. After the device turns off, press and hold the "Side" button again until the Apple logo appears.

The "Apple Face ID not working on iPhone" issue may also be caused by system bugs or software incompatibility. Updating your device to the latest version of iOS may resolve these problems.

Step 2. Click "Software Update" and wait for the device to check if it's updated to the latest version.
Step 3. If there is an update, click on "Download and Install". (iPhone stuck on software update?)

Step 1. Click on the "Settings" app to open it and look for "General". Click on it.
Step 2. On the General menu, click the "Transfer or Reset iPhone" option.
