Passkeys, the digital credentials that let you sign into apps and websites without entering a password, are getting easier to use for Chrome users.

You can now save passkeys to Google Password Manager, Google’s password manager built into Chrome on Windows, macOS, and Linux, so that your passkeys automatically sync across all your signed-in devices. The Password Manager client on Android can also now automatically sync passkeys, and syncing support for iOS is coming soon. (On ChromeOS, passkey syncing is in beta.)

As an added layer of protection, Google is adding PINs to Password Manager. When you start using passkeys on a new device, you’ll need to know either your PIN or the screen lock code for your Android device. You can set up a six-digit PIN or opt for a longer alphanumeric PIN.

“These recovery factors will allow you to securely access your saved passkeys and sync new ones across your computers and Android devices,” Chrome product manager Chirag Desai writes in a blog post.

Passkey usage is on the rise. According to the FIDO Alliance, the industry organization that develops authentication standards, 53% of people have enabled passkeys on at least one of their accounts, and passkeys are now supported by 20% of the world’s top 100 websites.

In 2023, Google made passkeys the default sign-in method for all users. More recently, the company brought passkey support to its Advanced Protection Program, a program for people at high risk of targeted attacks, like politicians and candidates, ahead of the U.S. presidential election.
