Google has expanded the sign-in options for its accounts to include a "selfie video", joining other face-based methods such as face unlock on a phone or biometric passkeys. It is meant as a backup route back into an account if a person's usual device is unavailable or other sign-in methods do not work, rather than a replacement for existing options.

Setting it up involves going to the Security & Sign-in section of a Google account, choosing the selfie video option, and following prompts using a computer's camera or a phone linked via QR code. Google asks users to remove glasses or masks, avoid cluttered backgrounds, and make certain head movements, which are intended to confirm a real person is present and to make the check harder to fool with deepfake videos or photos.

The change matters because it touches on the wider debate around biometric data and account security, as more services move away from passwords towards face and fingerprint-based verification. Google states the videos are encrypted, used only to verify identity at sign-in, and can be deleted by the user at any time; the option is not currently offered to Workspace accounts, child accounts, or those enrolled in Google's Advanced Protection Program.
