Windows Hello is a new feature on Windows 10 that enables you to ditch complicated passwords and sign-in to your account using just your face or fingerprint.
And computer manufacturers are quickly adopting Windows Hello by integrating infrared cameras and fingerprint readers into their new Windows 10 devices. However, there are millions of older PCs that have been upgraded to Windows 10 that unfortunately can take advantage of Windows Hello, because they haven’t been originally equipped with the require hardware.
Thankfully, Microsoft has already announced that it’s opening the framework for third-parties to start building their own biometric accessories. MouseComputer is one of company introducing two Windows Hello compatible accessories, including a compact infrared camera and a tiny fingerprint reader, which in either case, both connect very easily through a USB port.
These new Windows Hello accessories to enable users with older PCs to sign-in to Windows 10 without a password will be available later this Winter. No pricing or specific release date has been announced at the time of this writing.
