Face ID is one of Apple’s most convenient and secure features, allowing you to unlock your iPhone and authenticate apps with just a glance. However, when Face ID stops working, it can be frustrating and disruptive to your daily routine.
This comprehensive guide will walk you through the steps to troubleshoot and fix Face ID issues on your iPhone, ensuring you can get back to using this seamless authentication method.
Understanding Face ID and Common Issues
Face ID uses Apple’s advanced TrueDepth camera system to create a detailed 3D map of your face. This system includes several components:
- An infrared camera
- A flood illuminator
- A dot projector
- A proximity sensor
When you set up Face ID, your iPhone captures multiple angles of your face and converts them into a mathematical representation. To unlock your device, the TrueDepth camera captures an infrared image and compares it to the stored data.
Common reasons why Face ID might not be working include:
- Obstructions blocking the TrueDepth camera
- Software glitches or outdated iOS
- Improper face positioning or lighting
- Changes in your appearance
- Hardware issues with the TrueDepth camera system
Let’s explore how to address these issues step by step.
Quick Fixes for Face ID Issues
Before diving into more advanced troubleshooting, try these quick fixes:
1. Restart Your iPhone
A simple restart can often resolve temporary glitches affecting Face ID:
- For iPhone X and later: Press and hold the side button and either volume button until the power off slider appears.
- For iPhone SE (2nd generation) and earlier: Press and hold the side or top button until the power off slider appears.
- Drag the slider to turn off your iPhone.
- After your device turns off, press and hold the side button to turn it back on.
2. Reset Face ID
Resetting Face ID can help if the system is having trouble recognizing your face:
- Go to Settings > Face ID & Passcode.
- Enter your passcode.
- Tap “Reset Face ID.”
- Set up Face ID again by following the on-screen instructions.
If you encounter issues during this process, such as being prompted for a passcode to enable Face ID, check out our guide on resolving the “Your passcode is required to enable Face ID” issue.
3. Check for Obstructions
Ensure the TrueDepth camera has a clear view of your face:
- Remove any screen protectors or cases that might be covering the camera.
- Clean the front-facing camera and sensors with a soft, lint-free cloth.
- Make sure your face isn’t partially covered by masks, sunglasses, or other accessories.
If you suspect there might be an issue with your TrueDepth camera, refer to our article on troubleshooting TrueDepth camera problems.
4. Adjust Lighting and Positioning
Face ID works best in well-lit conditions with your face directly in front of the camera:
- Move to a brighter area if you’re in low light.
- Hold your iPhone 10-20 inches away from your face.
- Look directly at the screen, ensuring your eyes, nose, and mouth are visible.
Advanced Troubleshooting Steps
If the quick fixes don’t resolve your Face ID issues, try these more advanced solutions:
1. Update iOS Software
Keeping your iPhone’s software up to date is crucial for optimal Face ID performance:
- Go to Settings > General > Software Update.
- If an update is available, tap “Download and Install.”
- Ensure your iPhone is connected to Wi-Fi and has sufficient battery life before updating.
2. Reset All Settings
This option resets all your iPhone settings without erasing data:
- Go to Settings > General > Transfer or Reset iPhone.
- Tap “Reset” and then “Reset All Settings.“
- Enter your passcode to confirm.
- After the reset, set up Face ID again.
3. Set Up an Alternate Appearance
If your appearance changes frequently (e.g., with and without glasses), setting up an alternate appearance can help:
- Go to Settings > Face ID & Passcode.
- Tap “Set Up an Alternate Appearance.”
- Follow the on-screen instructions to scan your face in its alternate state.
4. Disable Attention Awareness Features
If you’re having trouble getting Face ID to recognize you, try turning off the requirement for eye contact:
- Go to Settings > Face ID & Passcode.
- Turn off “Require Attention for Face ID.”
Note that this may slightly reduce the security of Face ID.
Hardware-Related Face ID Problems
If you’ve tried all software troubleshooting steps and Face ID still isn’t working, you may be dealing with a hardware issue. The TrueDepth camera system is complex and sensitive, and damage to any of its components can cause Face ID to fail.
Signs of potential hardware issues include:
- Persistent error messages like “Face ID is not available” or “Unable to activate Face ID“
- Face ID not working after a screen replacement or other repair
- Visible damage to the front-facing camera area
If you suspect hardware issues, it’s best to seek professional repair services from Apple or an authorized service provider.
Using Alternative Authentication Methods
While troubleshooting Face ID issues, you can use these alternative methods to access your iPhone:
Enable Passcode Authentication
Always ensure you have a strong passcode set up as a backup:
- Go to Settings > Face ID & Passcode.
- Tap “Turn Passcode On” if it’s not already enabled.
- Choose a strong, unique passcode.

Set Up Touch ID (If Available)
For iPhone models with Touch ID:
- Go to Settings > Touch ID & Passcode.
- Tap “Add a Fingerprint” and follow the instructions.
