Shortly after Google launched the Pixel 4, it was found that its facial unlock mechanism was not particularly secure because it unlocked the device even if the user closed his eyes. This means anyone can point the Pixel4 to your face and open it while you sleep. The company has come under fire for this oversight, not least because the Pixel 4 has a dedicated infrared sensor on the front end that helps unlock the face.
At the time, Google promised to work to improve the face unlocking experience for the Pixel 4 series. Now, the company is starting to improve the security of facial unlocking on devices. According to Android Police, searching for Eyes in the Pixel 4’s Settings menu pops up the “Need to Open Your Eyes” option, indicating that you must open your eyes to unlock your face. This feature is not yet enabled, and clicking on the search results will take you to the regular face unlock menu.
Google is supposed to add the final touch estoin to the feature, which may explain why it appears in the Settings menu. The feature was supposed to be included in the security patch released earlier this week, but the company will be able to add it to the Pixel 4 series next month with a security patch in April.
