Up until now, you could only save passkeys to Google Password Manager on Android. You could use them on other devices, but you'd need to scan a QR code using your Android device. Today, we're rolling out updates that make it even easier to use passkeys across your devices. You can now save passkeys to Google Password Manager from Windows, macOS, Linux and Android, with ChromeOS currently available for testing in Beta. Once they're saved, they'll automatically sync across your devices, making signing in as easy as scanning your fingerprint.
