Passwords, combined with Google’s automated protections, help secure billions of users around the world. But, new security technologies are surpassing passwords in terms of both strength and convenience. With this in mind, we are happy to announce that you can verify your identity by using your fingerprint or screen lock instead of a password when visiting certain Google services. The feature is available today on Pixel devices and coming to all Android 7+ devices over the next few days.
These enhancements are built using the FIDO2 standards, W3C WebAuthn and FIDO CTAP, and are designed to provide simpler and more secure authentication experiences. They are a result of years of collaboration between Google and many other organizations in the FIDO Alliance and the W3C.
An important benefit of using FIDO2 versus interacting with the native fingerprint APIs on Android is that these biometric capabilities are now, for the first time, available on the web, allowing the same credentials be used by both native apps and web services. This means that a user only has to register their fingerprint with a service once and then the fingerprint will work for both the native application and the web service.
Note that your fingerprint is never sent to Google’s servers – it is securely stored on your device, and only a cryptographic proof that you’ve correctly scanned it is sent to Google’s servers. This is a fundamental part of the FIDO2 design.
Please follow the instructions below if you’d like to try it out.
- Phone is running Android 7.0 (Nougat) or later
- Your personal Google Account is added to your Android device
- Valid screen lock is set up on your Android device
To try it
- Open the Chrome app on your Android device
- Navigate to https://passwords.google.com
- Choose a site to view or manage a saved password
- Follow the instructions to confirm that it’s you trying signing in

For additional security
Remember, Google’s automated defenses securely block the overwhelming majority of sign-in attempts even if an attacker has your username or password. Further, you can protect your accounts with two-step verification (2SV), including Titan Security Keys and Android phone’s built-in security key.
Both security keys and local user verification based on biometrics use the FIDO2 standards. However, these two protections address different use cases. Security keys are used for bootstrapping a new device as a second factor as part of 2SV in order to make sure it’s the right owner of the account accessing it. Local user verification based on biometrics comes after bootstrapping a device and can be used for re-authentication during step-up flows to verify the identity of the already signed-in user.
