Chrome on Android tests biometric check before password autofill

Google has brought back a Chrome Canary flag called Biometric reauth for password filling, which requires biometric authentication before autofilling saved passwords. The feature has been tested since at least September 2024 and was previously pulled before reaching stable; it currently works only for some users.

• Flag Biometric reauth for password filling appears in Chrome Canary 157.0.8083.0
• Feature requires biometrics before autofilling a saved password
• Google has tested it since September 2024 and pulled it before stable
• It did not trigger on a Pixel 8 in testing, so rollout is limited
