What you need to know
- Google is testing a requirement for fingerprint or face scans before Chrome autofills saved passwords.
- After testing and pulling the feature over a year ago, Google revived it in the latest Chrome Canary build.
- The extra verification could prevent someone with an unlocked device from accessing all your saved website passwords.
Chrome on Android might soon be a little less trusting with password autofill.
It looks like Google is testing a biometric check for stored passwords in Chrome that would require your fingerprint, face unlock, or another supported method of confirming that it’s really you before Chrome auto-fills the password.
That change is back in the latest Chrome Canary build, with Google adding a “Biometric reauth for password filling” flag, first spotted by @Leopeva64 on X.

Over a year ago, Google tested a feature in Chrome for Android that required authentication before autofilling passwords, but it was removed shortly after and never reached stable. Well, this feature has been brought back in Canary and Google added a dedicated flag to enable it: https://t.co/h9x3XzvHzf pic.twitter.com/z0no85cmrtSeptember 30, 2026
When enabled, tapping a saved credential can trigger authentication before Chrome hands over the password. Thus, unlocking your phone may no longer be enough to unlock your entire password vault.
That extra step closes a security hole in Google Password Manager. While this security check is already available in apps for filling passwords with biometric protection, Chrome has handled autofill in the browser differently in the past.
Google previously teased this protection was coming to Chrome soon, and the Canary test shows the company is still working toward it.
In fact, Google has been circling this idea for a while. The feature was tested over a year ago but vanished before it got to Chrome’s stable channel. Now Leopeva64 has seen it again in Canary, with a flag for it, indicating the project is back on the table.
Interestingly, there is already biometric authentication for password autofill in iPhones. On Apple’s devices, Face ID or Touch ID can authenticate Password AutoFill when you fill saved usernames and passwords in Safari.
The difference is that the potential Chrome feature from Google seems to be targeted at bringing in biometric reauthentication at the point when Chrome goes into a saved password. Apple already has biometric authentication built into its password management and AutoFill system.
If Google does ship the feature, it would mean stealing an unlocked phone wouldn’t automatically provide you with access to every saved website password. For now, though, Chrome Canary is the testing ground, and Google hasn’t announced a stable release date.
