Apple introduced a mask-compatible Face ID feature in iOS 15.4, but it doesn’t work with sunglasses. For users who wear both masks and sunglasses, unlocking an iPhone can be frustrating. Fortunately, Apple Watch offers a seamless solution—allowing users to bypass passcode entry when Face ID fails.
How the Apple Watch Unlock Feature Works
This feature allows an iPhone to unlock automatically when Face ID detects a partially obscured face (such as one wearing a mask) while the paired Apple Watch is nearby and unlocked. Once activated, the Apple Watch provides haptic feedback and a notification confirming the iPhone has been unlocked.
Compatibility & Requirements
- Devices: iPhone X or later, Apple Watch Series 3 or newer.
- Conditions: Both devices must be in close proximity. Bluetooth and Wi-Fi must be enabled. Both devices must be signed in to the same Apple ID and have passcode protection. Wrist detection must be enabled on the Apple Watch.
How to Enable Unlock with Apple Watch
- Open Settings on your iPhone.
- Navigate to Face ID & Passcode.
- Scroll down to Unlock with Apple Watch and toggle on your Apple Watch.
Locking Your iPhone Manually
If the Apple Watch unlocks your iPhone unintentionally, you can quickly relock it:
- Tap the unlock notification on your Apple Watch.
- Select Lock iPhone to disable the feature until the next manual unlock.
Security Considerations
Apple has implemented multiple safeguards to ensure security:
- The Apple Watch must be unlocked and worn on the wrist.
- Face ID must first attempt (and fail) to recognize the user.
- Instant notifications allow users to relock the iPhone if needed.
Troubleshooting Tips
If the feature isn’t working, try these steps:
- Ensure Bluetooth and Wi-Fi are active on both devices.
- Verify that Wrist Detection is enabled in the Watch app.
- Restart both devices to resolve potential software glitches.
- If issues persist, contact Apple Support for further assistance.
Conclusion
While Face ID with a mask is useful, the Apple Watch unlock feature provides an extra layer of convenience—especially in situations where Face ID struggles. If you own a compatible Apple Watch, enabling this feature enhances both security and ease of use within the Apple ecosystem.
