Through the looking glass: As passwords continue to face criticism for being generally insecure or sometimes difficult to remember, tech giants have introduced numerous alternatives. Google's latest option resembles Apple's Face ID but is slightly more complex and can unlock accounts on multiple devices. Users in the wild will doubtlessly test its resilience against fraud.

Google account holders can now check their eligibility to test a new sign-in method that compares a selfie video with an encrypted version stored on the company's servers. Google aims to provide a last resort when users cannot remember passwords or utilize passkeys.

Eligible users can set up a selfie video by signing into their Google accounts and navigating to Security & sign-in > How you sign in to Google > Selfie video. On the page for adding a sign-in selfie, click or tap Continue and follow the onscreen directions. The company recommends that users record selfie videos alone and without sunglasses, masks, or hats. If users attempt to set up a selfie video on a PC or other device without a camera, a QR code can migrate the process to a smartphone or other camera-equipped device. Child accounts, Workspace accounts, and accounts in recovery mode are ineligible.
