Following April security updates, Microsoft discovered a software bug with Windows Hello that might make it impossible for users to log in using face recognition. The problem was a straightforward fix rather than a rise in helpdesk password reset requests.
According to Microsoft, this problem currently affects a subset of devices where either System Guard Secure Launch or Dynamic Root of Trust for Measurement (DRTM) is enabled on Windows 11 and Windows Server 2025 machines. This issue is caused by the KB5055523 update released on April 8.
The company stated, “After installing this update and performing a Push button reset or Reset this PC from Settings > System > Recovery and selecting Keep my Files and Local install, some users might be unable to login to their Windows services using Windows Hello facial recognition or PIN. Users might observe a Windows Hello Message saying ‘Something happened, and your PIN isn’t available. Click to set up your PIN again’ or ‘Sorry something went wrong with face setup.”
Analysts believe that the anticipated quick fix and temporary workaround could lower the number of trouble complaints and calls for businesses.
Windows Hello for Business, which launched biometric sign in Windows 10 and 11 business and enterprise users, first launched in November 2023.
It is a more personal and secure way to sign in to Windows device. Instead of using a password, with Windows Hello users can sign in using facial recognition, fingerprint, or a PIN.
Microsoft engineers are actively working on a permanent fix for the Windows Hello authentication issue.
