Best answer: If you want to increase login speeds and convenience on your Windows 10 or Windows 11 desktop or PC that doesn't have Windows Hello built in, then you should get a webcam with Windows Hello. If you need a camera for filming or streaming as well as unlocking your PC, Logitech's BRIO 4K is an excellent camera with high resolution. If you just need a camera to unlock your PC, the Kaysuda CA20 works well and is cheaper, though the picture quality is worse.
