One of the features of Apple’s Face ID is that it doesn’t work if your eyes are closed. Apple calls it an “attention” requirement and it makes sense, where Touch ID could be used even when you’re asleep, Face ID can’t. It’s supposed to be more secure, but it seems that Google’s Pixel 4 face unlock feature isn’t quite up to scratch.
This is according to multiple reports in which users are discovering that face unlock can be beaten even when the owner’s eyes are closed. Now, to be fair, Google did warn in supporting document that the face unlock could be beaten if your eyes are closed, and warn users about keeping their phones in a secure location.
“Your phone can also be unlocked by someone else if it’s held up to your face, even if your eyes are closed. Keep your phone in a safe place, like your front pocket or handbag.”
We’re not sure why the Pixel 4’s security system isn’t as robust compared to Face ID, but it could be because of the different technology Google chose to use with the phone. In any case, if you do plan on getting your hands on the Pixel 4, you might want to consider using a different form of security if you feel that maybe the face unlock feature is still not up to scratch based on your standards.
