GoKawiilGoogle tests biometric check for Chrome Android password autofill
Google is experimenting with a Chrome Canary flag called 'Biometric reauth for password filling' that requires a fingerprint or face scan before autofilling saved passwords on Android. The feature appeared in version 157.0.8083.0 and was spotted by browser researcher Leopeva64, who demonstrated it triggering an authentication prompt. Google previously tested a similar feature in 2024 before pulling it ahead of a stable release.
GoKawiil's interpretation of the reporting above, not reported fact.
Requiring biometric confirmation before autofill could add a security layer against someone else picking up an unlocked phone and accessing saved logins. The feature's inconsistent behavior—working for some testers but not triggering on other devices like a Pixel 8—suggests Google is still refining a staged or incomplete rollout rather than preparing for imminent wide release.
- Chrome Canary includes a new 'Biometric reauth for password filling' flag on Android.
- The feature doesn't yet work consistently across devices, testing inactive on a Pixel 8.
- Google previously tried and withdrew a similar feature before it reached stable Chrome.
