Google is testing a biometric authentication requirement for Chrome password autofill on Android in the latest Chrome Canary build. The feature, which requires fingerprint or face scan before filling saved passwords, was previously tested over a year ago but removed before reaching stable. Now revived with a dedicated 'Biometric reauth for password filling' flag, it aims to prevent unauthorized access to saved passwords even if the device is unlocked.
When enabled, tapping a saved credential triggers authentication before Chrome releases the password, closing a security gap in Google Password Manager. This mirrors existing biometric protection in iOS Safari, where Face ID or Touch ID secures password autofill. Google has been circling this idea for some time, and the Canary test confirms ongoing development.
No stable release date has been announced, but the feature’s return signals Google’s continued focus on strengthening browser-based password security.
