Windows Hello no longer recognises you in the dark: Microsoft has changed how facial recognition login works
Microsoft has released a Windows 11 update that disables the ability to use the Windows Hello feature in dark and dimly lit areas.
Here's What We Know
Microsoft explained that the previous principles of Windows Hello allowed attackers to bypass authentication and gain access to users' personal data.
To eliminate this possibility, the company has disabled the option of facial recognition in low-light conditions. The changes affect devices that use an infrared camera without confirmation from a colour sensor.
Windows Hello now requires the infrared and regular RGB camera to function simultaneously, making it impossible to sign in in a dark room.
To get around this limitation, users can disable the regular camera in Device Manager, but obviously this will make it impossible for other applications that require the camera to work.
While Microsoft's decision is motivated by a desire for security, it has provoked a negative reaction from many users, especially owners of compact Surface laptops who are used to fast and contactless logins in all conditions.
It remains to be seen if Microsoft will find a way to bring back night mode without weakening security.
