Google just added selfie video as a sign-in and account recovery option.
You can now prove it’s you with a short selfie video designed to resist photos and deepfakes. To fend off deepfakes and impersonation attempts, it requires you to turn your head to prove you are really in front of the camera.
They also encrypt the video and only use it for login purposes.
