Google to Add Passwordless Authentication Support to Android and Chrome

Google today announced plans to implement support for passwordless logins in Android and the Chrome web browser to allow users to sign in across different devices and websites irrespective of the platform.

"This will simplify sign-ins across devices, websites, and applications no matter the platform - without the need for a single password," Google said.

Apple and Microsoft are also expected to extend the support to iOS, macOS, and Windows operating systems as well as Safari and Edge browsers.

The new Fast IDentity Online (FIDO) sign-in system does away with passwords entirely in favor of displaying a prompt asking a user to unlock the phone when signing into a website or an application.

This is made possible by storing a cryptographically secured FIDO credential called a passkey on the phone that's used to log in to the online account after unlocking the device.

"Once you've done this, you won't need your phone again and you can sign-in by just unlocking your computer," Google said.

"Even if you lose your phone, your passkeys will securely sync to your new phone from cloud backup, allowing you to pick up right where your old device left off."

In a way, the method can be viewed as an extension of its own Google prompts for logging into accounts secured with two-factor authentication (aka 2-Step Verification).

The development comes as code hosting platform GitHub announced that it will "require all users who contribute code on GitHub.com to enable one or more forms of two-factor authentication (2FA) by the end of 2023" to prevent account takeover attacks.
