How to Reset Face ID

Apple’s Face ID is a marvel of modern biometric technology, offering an easy and secure way to unlock iPhones, sign into apps, and authorize purchases. However, like all technology, there are times when it may not work as expected. If you’re wondering, “How to reset Face ID?” then this comprehensive guide is for you. Whether you’re facing recognition issues or just want to start afresh, resetting Face ID can often help. Let’s dive deeper into understanding how to reset Face ID and when it might be beneficial to do so.

Understanding Face ID

Before we delve into the steps on how to reset Face ID, it’s essential to grasp how this technology works. Introduced with the iPhone X, Face ID uses a combination of infrared emitters and sensors to map your face’s unique characteristics. This TrueDepth camera system projects over 30,000 invisible dots onto your face, captures their reflection, and then uses this data to create a detailed 3D model.

Why Might You Need to Reset Face ID?

  1. Recognition Issues: Over time, you might find Face ID doesn’t recognize you as quickly or fails occasionally. Resetting can help recalibrate and improve accuracy.
  2. Major Appearance Changes: If you’ve undergone significant changes in your appearance, such as facial surgery or growing a substantial beard, resetting Face ID can be beneficial.
  3. Privacy Concerns: If someone else has had access to your device and could have set up their face, you’d want to know how to reset Face ID to maintain security.
  4. Device Selling or Transfer: If you’re giving away or selling your iPhone, resetting Face ID ensures the next user starts from scratch.

How to Reset Face ID: A Step-by-Step Guide

So, how do you reset Face ID? The process is straightforward:

  1. Open Settings:
    • From your iPhone’s home screen, tap on the ‘Settings’ icon.
  2. Navigate to Face ID & Passcode:
    • Scroll down in the Settings menu until you find ‘Face ID & Passcode’. Tap on it.
    • You’ll be prompted to enter your passcode. Do so to proceed.
  3. Reset Face ID:
    • Once inside the Face ID & Passcode settings, you’ll see an option that says ‘Reset Face ID’. Tap on this option. This action will delete the facial data Apple has stored for you.
    • After resetting, if you’re still keen on using Face ID, you’ll have to set it up again, as if for the first time.
  4. Re-setup Face ID:
    • In the same ‘Face ID & Passcode’ settings, tap ‘Set Up Face ID’.
    • You’ll be prompted to position your face in the camera frame and move your head in a circle. This process captures the facial data from various angles.
  5. Ensure Other Settings Are Correct:
    • While you’re learning how to reset Face ID, it’s a good time to check other settings too.
    • Ensure that ‘iPhone Unlock’ and other desired actions are toggled on under the ‘Use Face ID For’ section.

Tips for an Accurate Face ID Setup

When you’re resetting and setting up Face ID again, consider these tips for optimal performance:

  • Good Lighting: For the initial setup, ensure you’re in a well-lit area but avoid direct sunlight.
  • Face Position: Hold your device 10-20 inches away from your face, roughly at arm’s length.
  • Natural Appearance: Set up Face ID in the way you look most of the time. If you regularly wear glasses or contacts, have them on.

What If Resetting Doesn’t Help?

If after understanding how to reset Face ID and going through the process, you still face issues, consider the following:

  • Check for Obstructions: Ensure there’s nothing covering the TrueDepth camera. Clean the camera if it looks smudgy.
  • Software Update: Sometimes, updating to the latest iOS version can solve glitches.
  • Visit Apple Support: If you’ve tried to reset Face ID multiple times without success, it might be time to consult with Apple directly.


Now that you have a comprehensive understanding of how to reset Face ID, you can confidently troubleshoot any Face ID issues you encounter. The security and convenience Face ID provides are unmatched, and with regular updates, Apple continues to refine and improve this technology. So, the next time you or a friend are pondering, “How do you reset Face ID?”, you’ll know exactly what to do. Happy unlocking!
