Google wants your face to be your backup password with new selfie video sign-in

Credit: Joe Hindy / Android Authority TL;DR Google is introducing a new selfie video sign-in and account recovery method that lets users verify their identity with a short selfie video. The feature uses liveness checks, facial matching, encryption, and Google’s existing security systems to help prevent spoofing attempts. Users can delete their saved selfie video at any time and can choose whether or not Google can use their videos to improve its facial recognition and verification tech.
