The new "selfie video" option works by asking users to record a short video while following simple on-screen head movements. The encrypted recording is securely stored with the user's permission and serves as a backup authentication method if they are ever locked out of their account or lose access to their trusted devices.
When users need to recover their account, Google compares a new live selfie video with the previously saved recording. The system includes liveness detection and several anti-spoofing technologies to help distinguish genuine users from fake photos, replay attacks or AI-generated deepfakes.
Google emphasized that users remain in control of their biometric data. The selfie video is encrypted at rest, can be deleted at any time from Google Account settings, and is used only for sign-in unless users separately choose to allow additional uses.
Google said the feature is gradually becoming available to eligible personal Google Accounts. However, it is not currently supported for Google Workspace accounts, child accounts or users enrolled in the Advanced Protection Program.
