Google has introduced a new authentication feature that enables users to verify their identity through facial recognition via selfie video. The mechanism allows account holders to regain access if they forget passwords, lose access to their devices, or cannot use their standard two-factor authentication methods.
The setup process requires users to record a reference video by looking at their device’s camera while following on-screen instructions. These instructions guide users through a series of head movements to capture their face from multiple angles, similar to the enrollment process for Apple’s Face ID but without requiring specialized infrared hardware.
Google stores the reference video in encrypted cloud storage, making it accessible across devices. Users retain control over the stored video and may delete it at any time through their account settings. The company notes that while the primary function is sign-in verification, users have the option to allow the video to be used for additional purposes as well.
The authentication process requires users to record a new selfie video during login to prove the video is being captured in real time. Google incorporates multiple security measures designed to prevent impersonation attempts using static images or synthetic deepfake videos, in addition to implementing standard security protocols to block suspicious sign-in attempts.
The feature is being rolled out gradually to users across the globe. Those interested in checking eligibility or setting up the feature can visit g.co/signin-selfie.
