Google has introduced a new selfie video verification feature that enables users to securely recover access to their accounts if they are locked out, forget their password, or lose access to their usual device or two-factor authentication methods.

According to The Verge, the new feature allows users to record a short video of their face using a mobile device or computer. Google then compares the new recording with a previously stored reference video to verify that the person attempting to sign in is the legitimate account owner.

To set up the feature, users are required to look into their device’s camera and follow on-screen instructions, including simple head movements. These movements help capture multiple angles of the user’s face, improving the accuracy of identity verification.

In an official blog post, Google said the setup process is similar to facial authentication systems such as Apple’s Face ID, although it does not rely on specialised infrared hardware.

The company said the reference selfie video is “recorded and securely stored” in the cloud using encryption. Users can delete the stored video at any time through their account settings. Google added that, by default, the selfie video is used only for sign-in verification, although users can choose to allow its use for additional purposes.

During account recovery or sign-in, users will be asked to record another short video while performing simple guided movements. This enables Google to confirm that the recording is being captured live and compare it with the stored reference video.

Google said the feature incorporates multiple security measures to prevent impersonation attempts using photographs, pre-recorded videos or AI-generated deepfakes. It also employs its standard security systems to detect and block suspicious sign-in attempts.

The selfie video verification feature will be rolled out gradually to users worldwide. Those interested can check its availability and enable the feature by visiting g.co/signin-selfie.
