Chrome, autofill, and biometric security One of the recently added Android features is biometric-protected autofill. It should enable something similar to iOS, where credit card numbers and passwords are protected by a fingerprint or Face ID.
However, with Chrome at least, this feature seems to not work: even if biometric security is enabled, no such auth is requested when autofill login forms (ie: with password autofill).
So: is it possible to enable biometric-protected password fills in Chrome with Android 10?
At the time of this writing (v87, Dec 2020), Chrome for Android doesn't support biometric-protected credential autofill.
This has been reported on Chromium Issue Tracker #1139045 - Security Feature: Only auto-fill passwords after user provides fingerprint or PIN on Oct 16, 2020, and acknowledged by a Chromium contributor.

we could potentially implement a feature where Chrome auto-fills passwords only after the user supplies their fingerprint or PIN. (Safari on iOS has this: https://support.apple.com/en-us/HT208109) I'll change this bug to a feature request.
