Microsoft tests Windows Hello sign-in that accepts PIN while face or fingerprint scans run
Microsoft is testing a Windows Hello change in Windows 11 Insider builds that lets users type their PIN while face or fingerprint recognition is still running, and whichever method succeeds first unlocks the session. The change is in Experimental build 26340.9882 (26H2), released to Insiders on November 6, 2026, and it is rolling out gradually, so not every tester will see it at once. After a restart, and at certain other times, Windows still asks for the PIN first. A separate option that temporarily brightens the screen for face sign-in in dim rooms appears in the 26H1 Experimental build 28120.3454 and in Beta build 26320.9876, not in 26340.9882 as the article implies. The threat level is low: this is a preview usability feature, it involves no vulnerability, CVE or exploitation, and sign-in still requires one of the user's enrolled Windows Hello methods.
Detalhes técnicos
- Per search excerpts of the Insider release notes for build 26340.9882 (neowin.net, digitalcitizen.life, windowslatest.com; pages not opened), sign-in and unlock accept face, fingerprint or PIN, whichever responds first. The Microsoft changelog for 26340.9882 itself could not be opened during this research.
- The brightness option is documented on Microsoft's own page for build 28120.3454 (learn.microsoft.com): it is enabled under Settings > Accounts > Sign-in options > Facial recognition (Windows Hello) with the switch "Automatically adjust screen brightness during face recognition", and it briefly raises brightness when the user is in a dark or dimly lit room.
- Conflicting Reports: the article presents the brightness toggle as part of the same update as the concurrent PIN change. The Microsoft page for 28120.3454 lists it under that build, and search excerpts place it in Beta build 26320.9876 (digitalcitizen.life, windowsforum.com). The article's statement that a production rollout reaches Windows 11 "early next year" is not stated in any Microsoft page opened here; no date was found.
