Can you unlock iPhone with eyes closed?

Answered by John Hunt

It is possible to unlock an iPhone with Face ID when your eyes are closed. This is because Face ID relies on the TrueDepth sensors located in the notch at the top of the iPhone’s screen to create a unique depth map of your face. These sensors project infrared dots onto your face and then capture the pattern of those dots with an infrared camera.

When Face ID was first introduced, it required the user’s attention in order to unlock the iPhone. This meant that your eyes had to be open and looking directly at the device for it to recognize your face and unlock. However, with an update to iOS, Apple introduced the option to turn off attention detection.

When attention detection is turned off, Face ID can still unlock your iPhone securely. The TrueDepth sensors will still accurately map your face and determine if it matches the enrolled face data. The only difference is that now, Face ID will work even if your eyes are closed. This can be useful in situations where you may be lying down, wearing sunglasses, or simply prefer to keep your eyes closed while unlocking your phone.

It’s important to note that turning off attention detection does not compromise the security of Face ID. The TrueDepth sensors still ensure that they are seeing your face and not a photograph or a mask, so the unlocking process remains secure. Apple has designed Face ID to be highly accurate and reliable, even with attention detection turned off.

Personal experiences may vary, but in my own usage of Face ID with attention detection turned off, I have found it useful when I’m lying in bed and want to quickly unlock my iPhone without needing to open my eyes fully. It provides added convenience without compromising security.

Face ID can unlock an iPhone with eyes closed when attention detection is turned off. This feature provides flexibility and convenience without compromising the security of the unlocking process.
