Google is introducing a new system that allows you to log into your Google account using a selfie video. To start using this system, you need to look at your phone or device's camera and move your head from various angles—left, right, up, and down—while recording an initial selfie video.

Once you've set this up, when you forget your password, you'll be able to log into your account by recording a new selfie video. Google will compare the newly recorded video with the originally stored video and verify whether you are the account owner.
If the selfie video stored in your account is no longer needed, you can delete it whenever you want. For security purposes, the data is systematically protected with encryption (encryption systems). Additionally, to prevent fake photos or videos from being used to gain unauthorized access to the account, multiple layers of security systems have been put in place.
