After reading the WC article about YubiKey I got really excited about physical 2FA! But, then I realized that neither of my computers have Windows Hello because are both from 2014. So, I was wondering, because YubiKey has nothing to do with the biometrics that are usually used with Windows Hello, is there a way I can force my Dell Inspiron 15 5000 and Surface Pro 3 to have Windows Hello so I can use YubiKey with them to log into my computer or it wont work because is there physcial hardware YubiKey needs to communicate with that wouldnt be on non-Windows Hello computers? Thank you so much for your help! I figure its a long shot, but I dont see why I wouldnt be able to do this, if there is no special hardware YubiKey needs to communicate with to do the authentication.
