Google is rolling out a new feature, called “Verify it’s you,” that allows you to log in to both native applications and web services by registering your fingerprint or any other method you’ve set up to unlock your Android device. The feature takes advantage of Android’s built-in FIDO2 certified security key feature that Google rolled out earlier this year to all devices running Android 7.0 Nougat or later. Google is working on expanding and adding this functionality to more Google and Google Cloud services in the near future.
