Last week, we reported about a flaw in Pixel 4’s Face Unlock system which can unlock the phone even when the device owner’s eyes are closed, meaning anyone could easily unlock a device while the owner of the device is sleeping. Google later confirmed the issue and argued that Pixel 4 face unlock meets the security requirements as a strong biometric, and can be used for payments and app authentication, including banking apps. Even with the flaw described above, Google’s Face Unlock system is resilient against invalid unlock attempts via other means, like with masks.
Google has now confirmed that they are working on delivering an update that will provide an option for users to require their eyes to be open to unlock the phone, and it will be available in the coming months.
In the meantime, if you are concerned about Pixel 4’s Face Unlock flaw, Google recommends you to activate pin, pattern or password for the phone unlock.
