Android 11 DP2 fixes the Pixel 4's big face unlock security issue

Pixel 4 XL back in hand 2

The Pixel 4 and Pixel 4XL were the first Google devices to use 3D face unlock. In general, the feature is much more secure than the standard 2D face unlock, because it is much harder to fool something with depth data versus a 2D image from a regular camera.

While it was great to see some updated security on Google devices, people quickly became concerned when they noticed you can unlock the phones without your eyes being open. This led to concerns about privacy and worries that someone might unlock your phone while you’re sleeping. While this is an incredibly unlikely scenario, it’s a valid concern and seems like a pretty obvious security oversight.

Google Pixel 4 requre eyes to be open setting

It seems like Google heard these complaints because the feature now requires eyes to be open in Android 11 DP 2. In the face unlock menu, you’ll now see a toggle that allows you to require eyes to be open to unlock your device. I don’t see any reason not have to this feature on all the time, and Google should probably make it standard.

Regardless, we’re really glad to see the feature go live. If you want to use it yourself, you’ll have to download the Android 11 Developer Preview 2 on a Pixel 4 or Pixel 4 XL. Are you happy the feature is finally here?
