About this tag
Windows Hello is Microsoft's passwordless sign-in system for Windows 10 and Windows 11, covering fingerprint, facial recognition, PIN, and picture passwords. Recent discussions focus on troubleshooting fingerprint sign-in issues, including driver and Windows Biometric Service repairs, and the distinction between standard Windows Hello and Enhanced Sign-in Security (ESS), which is expanding to external fingerprint readers in Windows 11 updates. Security topics include CVE-2026-61928, a Windows Hello tampering vulnerability patched in August 2026, and research on Windows Hello for Business risks, such as malware requesting Entra PRTs in unlocked sessions. Microsoft has also ended new picture-password enrollment in Windows 11 24H2 and 25H2, while existing picture passwords remain unaffected.

    Windows Hello Face: Fix ‘Couldn’t Recognize You’ Errors

    Windows Hello Brightens Screen for Low-Light Face Sign-In

    Microsoft has documented a Windows 11 behavior that can make Windows Hello face sign-in work in dark rooms: when the system decides there is too little ambient light, it can temporarily raise the display brightness and use the screen itself to illuminate the user’s face. The setting, published...

    Fix Windows Hello Fingerprint Sign-In and Missing Reader

    Windows Hello fingerprint sign-in can usually be restored without resetting Windows, but the right repair depends on whether the reader still appears in Device Manager.

    KB5101650 Ends New Windows 11 Picture Password Enrollment

    Microsoft has ended new picture-password enrollment in Windows 11 24H2 and 25H2, but the change is narrower than early reports suggested: it does not remove existing picture passwords, and Microsoft’s own update record does not list Windows 10 among the affected products. Neowin first...

    Windows Hello for Business Lets Malware Request Entra PRTs

    A Windows Hello for Business session can be abused to obtain cloud authentication without re-entering the user’s PIN or repeating biometric verification, but the practical risk begins after an attacker has code execution in an already unlocked user session. The technique does not extract a...

    Windows sign-in options are meant to make a PC both faster to unlock and harder for anyone else to access.

    Microsoft Entra ID SMS and Voice MFA Retire February 1, 2027
