Google Accounts are introducing a new "selfie video" sign-in method designed as a backup for situations where users lose their phone or passkeys. The setup requires users to record a short video of themselves performing guided head movements, capturing various angles. This feature is accessible on both mobile and desktop devices, with users without PC cameras able to authenticate via their phones.

To regain access to a locked account, users will record another selfie video, which Google will compare against the saved recording. The system verifies the user by requiring them to replicate simple movements, ensuring it's a live video and not a pre-recorded fake or deepfake. Google emphasizes "multiple layers of security" to combat impersonation attempts, alongside other checks for suspicious sign-ins.

Users have the option to delete their selfie video at any time. By default, it's solely for sign-in purposes, but an opt-in allows the data to enhance verification methods. The selfie video is encrypted at rest. This new method joins existing options like passkeys and recovery contacts, and Google recommends setting up multiple sign-in methods. Eligibility and setup can be managed at g.co/signin-selfie.
