How to Unlock iPhone Face ID While Sleeping

In today’s fast-paced world, we rely heavily on our smartphones, and the iPhone, with its Face ID feature, has revolutionized the way we secure our devices. However, have you ever found yourself in a situation where you need to unlock your iPhone using Face ID while you’re still half-asleep? Perhaps you’ve experienced the frustration of your iPhone not recognizing your face in such moments. Fear not, as this article will guide you on how to unlock your iPhone with Face ID effortlessly, even when you’re in a deep slumber.

Understanding Face ID

Before delving into the tricks to unlock your iPhone while sleeping, let’s first understand how Face ID works. Apple’s Face ID is a facial recognition system that uses a sophisticated True Depth camera to create a 3D map of your face. It’s designed to enhance security by ensuring that only you can access your device.

How Face ID Functions

  1. Face Scanning: When you raise your iPhone, the True Depth camera scans your face with infrared and visible light to create a facial map.
  2. Comparison: The facial map is then compared to the one stored securely on your device. If there’s a match, your iPhone unlocks.
  3. Attention Awareness: Face ID also checks if you’re actively looking at the device, adding an extra layer of security.

Unlocking Face ID While Sleeping

Unlocking your iPhone using Face ID while sleeping might seem counterintuitive, but there are situations where it can be beneficial. For instance, you may need to check the time or dismiss an alarm without fully waking up. Here’s how you can do it:

1. Raise to Wake

The “Raise to Wake” feature is incredibly handy when you want to check notifications or the time without unlocking your iPhone. Simply lift your iPhone, and the screen will wake up. This feature works whether you’re awake or sleeping.

2. Disable Attention Awareness

To prevent Face ID from requiring your full attention, you can disable the “Attention Awareness” feature. Here’s how:

  • Go to “Settings.”
  • Scroll down to “Face ID & Passcode.”
  • Enter your passcode.
  • Toggle off “Attention Awareness.”

With this feature turned off, Face ID will unlock your iPhone even if your eyes are closed.

3. Use an Alternate Look

Face ID allows you to set up an “Alternate Appearance.” This can be useful if you want to unlock your iPhone while sleeping or with a different look, such as when wearing sunglasses. To set up an Alternate Appearance:

  • Go to “Settings.”
  • Scroll down to “Face ID & Passcode.”
  • Enter your passcode.
  • Choose “Set Up an Alternate Appearance” and follow the prompts.

4. Enable “Rest Finger to Open”

If you’d rather use your fingerprint to unlock your iPhone while sleeping, enable the “Rest Finger to Open” feature:

  • Go to “Settings.”
  • Select “Accessibility.”
  • Tap on “Touch.”
  • Enable “Rest Finger to Open.”

Now, you can simply rest your finger on the home button to unlock your device.


Unlocking your iPhone with Face ID while sleeping may not be the most common scenario, but it’s good to know these techniques for those moments when you need quick access without fully waking up. With features like “Raise to Wake,” “Alternate Appearance,” and “Rest Finger to Open,” you can ensure that your iPhone is a helpful companion even during your slumber.
