“This will simplify sign-ins across devices, websites, and applications no matter the platform – without the need for a single password,” Google said.
The new Fast IDentity Online 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.
