Problems with Pixel 4

Google has already confirmed the problemssecurity of the facial authentication system in the new Pixel 4, recognizing that the technology can unlock the device even when the user's eyes are closed.

Early reviews of the Pixel 4 were mostlypositive. Many have praised the phone for its super-fast new face unlock system, which replaces the fingerprint scanner and works almost exactly like Apple's Face ID on the iPhone. However, the BBC discovered that the Pixel 4 can be unlocked with the user's face, even if they are sleeping (or pretending to be asleep). This is markedly different from Apple's Face ID system, which requires the user's eyes to be open to unlock the iPhone. Although iPhone users can disable this attention feature for convenience, it is always enabled by default. The Pixel 4 doesn't have it at all.

By the way, Google, however, does not hide this fact. The Google support page states: “Your phone can also be unlocked by someone else if it is held up to your face, even if your eyes are closed. Keep your phone in a safe place, such as in your front pocket or purse. ”

To “prepare for unsafe situations,”Google recommends holding the power button for a few seconds and pressing “Lock”, which disables notifications and unlocks face recognition.

In the early leaks, the Pixel 4 in the screenshots wasthe “require eyes open” setting to unlock the face is shown. It is possible that Google tried to implement a function similar to Apple Attention Aware, but did not modify it at the time of launch.

Speaking at the Google Pixel 4 presentation, managerPixel Products Sherry Lin said, “There are really only two face [authentication] solutions that meet the bar for ultra-security. So, you know, for payments this level — ours and Apple.”

Cybersecurity experts disagreeby this statement. “If someone can unlock your phone while you sleep, that's a big security issue,” — security blogger Graham Cluley told the BBC. In a statement relayed to the BBC, Google said it would "continue to improve Face Unlock over time."
