my dell xps m1530 with face recognition software

ive been looking for the right software, as for right now, my laptop already have a fingerprint security hardware, but thinking, " i can use face verification, why not?", so ive put in the software that utilises my webcam, so right now there are 3 (three) layers of security to access my laptop....too much you think? i think for a laptop with A LOT of information, its not enough..the software looks just like this...
