Google has incorporated a new way to log in using a video selfie. The company announced this on Thursday and joins the wave of tech companies that are betting on biometrics over passwords to verify online identity.
According to Google, this option aims to provide more alternatives for users who find themselves locked out of their account or do not have access to their usual phone or computer. The system adds to the existing access methods.

How the video selfie login works
To set up the feature, the user must look at the device's camera and complete a series of guided movements. These include turning the head to the right or left, or nodding.
These gestures allow capturing different angles of the face. If later the user has trouble logging into their account, they can record a new video selfie and Google compares it to the one recorded during setup.
How Google prevents impersonation attempts
The main challenge that Google seeks to address is confirming that there is a real person on the other side of the camera, and not a bot or a manipulated video. The company explained that it applies multiple layers of security for this.
