Quote:Google is rolling out biometric authentication for autofill of login credentials in Android. While Android has had Google's autofill feature for a couple of years now, the implementation was insecure since Google never asked for biometric verification or a password before filling in the details. This meant that one could easily use the autofill feature to log into apps and services on an unlocked device.
 
With a recent Play Services update and a server-side switch, Google has rolled out biometric authentication for autofill on Android 10 and newer devices. The feature is hidden under Settings -> Google -> Auto-fill -> Auto-fill with Google -> Auto-fill security. Here, you will find the option to toggle biometric authentication for login credentials, though it was enabled by default on my Galaxy S20+.
 
Below is a quick video from Android Police showing the feature in action:
