Fix 1: Ensure Your Face Is Fully Visible

Face ID works best when your face is fully visible and unobstructed. Make sure you’re not wearing sunglasses or a mask that could block your face from being recognized. If you’re in a low-light environment, try moving to a brighter area, as Face ID may struggle to recognize you in poor lighting.

Fix 2: Add an Alternate Appearance

If Face ID is still acting up, it might be worth adding an alternate appearance. This feature is particularly useful if your appearance has changed significantly since you first set up Face ID.

Steps to Add an Alternate Appearance:

1. Go to Settings > Face ID & Passcode.
2. Enter your passcode.
3. Tap Set Up an Alternate Appearance.
4. Follow the on-screen instructions to scan your face again.

Fix 3: Reset Face ID

If you’re still experiencing issues, resetting Face ID might be the next best step. This can help clear any glitches or errors that might be causing the problem.

Steps to Reset Face ID:

1. Go to Settings > Face ID & Passcode.
2. Tap Reset Face ID.
3. Tap Set Up Face ID to scan your face again.
