Here’s a summary of the Gagadget.com article regarding the Windows Hello change:
What’s Happened:
- Microsoft has released an update for Windows 11 that changes how Windows Hello facial recognition works: it is now disabled in dark or low-light conditions.
- Previously, Windows Hello could be tricked under certain lighting conditions, making it possible for attackers to bypass authentication and gain access to personal data.
- To enhance security, facial recognition is now only available when both the infrared and regular RGB cameras are working. This effectively prevents Windows Hello from working in darkness.
- Devices using only an infrared camera (without confirmation from a color sensor) are primarily affected.
- If you attempt to log in using Windows Hello facial recognition in the dark, it will not work anymore unless there’s enough light for the RGB sensor to operate alongside the IR camera.
- You could technically disable the regular camera in Device Manager, but then all apps needing the camera would stop working.
- Many users, especially those with compact Surface laptops who rely on Windows Hello for quick, contactless login, are frustrated by this change.
- The company says this is about improving user safety and security.
- It is not considered a bug, but a security-motivated feature.
- It remains to be seen if Microsoft will find a way to restore login in darkness without compromising security.
