Google now lets you sign in to your account using a selfie video

Google introduced a new account access method using a selfie video to verify identity, useful for account recovery and multi-factor authentication. This feature can be used when locked out, password forgotten, or without access to typical authentication methods. To set it up, follow onscreen prompts to capture multiple angles of your face. This adds an alternative to traditional account recovery methods. It's available on mobile devices and PCs.
