Face ID is one of the most convenient and secure methods on modern iPhones that can unlock the screen or pay for purchases. Introduced with the iPhone X and continuously refined across newer models, Face ID enables you to unlock your phone, sign in to apps, and authorize purchases — all simply by looking at your device. However, what if your appearance changes drastically? Or you want to register a different look? In this article, we'll go through everything you need to know about how to change Face ID on iPhone correctly.

Part 1: What Does Changing Face ID on iPhone Mean?

Before we jump into how to change Face ID on iPhone, it's important to understand what you can do with Face ID. Apple allows you to do two primary things:

Reset Face ID completely: This will delete all existing face data and allow you to rescan your face from scratch to create a new Face ID.

Set up an alternate appearance: If you often wear glasses, hats, makeup, or other wearings, this option allows you to add a second face profile without removing the existing one.

Part 2: How to Reset and Change Face ID Completely

If your iPhone is not recognizing you as well as before — perhaps after a significant change to your appearance — you can change Face ID on iPhone. Here's how:

Step 1. Open the Settings app on your iPhone.

Step 2. Scroll down and tap on the Face ID & Passcode button. Enter your device passcode if prompted.

Step 3. Tap the Reset Face ID button. This will immediately delete all previously saved face data. Now, tap the Set Up Face ID button.

Step 4. Now, you should follow the on-screen instructions to change or redo Face ID on iPhone. Position your face inside the camera frame, and then move your head slowly in a circle as instructed to capture every angle of your face.

Step 5. After completing the first scan, tap Continue. Repeat the scanning process one more time. Once the setup is successful, tap the Done button. You've learned how to change Face ID on iPhone 13, 14, 15, 16, or 17.

Bonus: Tips for Getting the Best Face ID Scan

This article has told you how to change Face ID on iPhone, but you still need to pay attention to some important factors that have a great influence on your Face ID scan.

1. Proper Lighting

Face ID works best in even, bright light. Avoid direct overhead lighting or harsh shadows when you redo or set up an alternative appearance.

2. Keep the Camera Clean

Smudges or dirt on the front iPhone camera may cause Face ID to fail. Even if you've successfully changed the Face ID on your iPhone, you may constantly fail to unlock the screen with this poor Face ID.

3. Avoid Extreme Angles

Hold the iPhone 10–20 inches away and straight in front of your face. Move your head slowly in a circle as instructed to capture all angles. Follow the on-screen guides when you change Face ID on iPhone.

4. Keep Your Eyes Open

By default, Face ID requires attention to unlock. Make sure your eyes are looking at the screen.

Part 3: Easily Remove Face ID Without Changing Face ID on iPhone

If you've forgotten the screen passcode on your iPhone, or your Face ID or Touch ID cannot work, how can you unlock your iPhone and change the Face ID? You should use Apeaksoft iOS Unlocker to easily remove the screen passcode, Touch ID, and Face ID. You only need to connect your iPhone to your computer, and this ultimate program can help you break through your iPhone with a few clicks.
