Ever wanted to login using just your face without typing anything or using biometric fingerprint scanners or so? It used to be sci-fi only, but now you can!
You can use Luxand Blink (FREE, PC Windows Vista and 7 32-bit ONLY) so that you can do that now. Of course, a webcam is needed to be attached and working. Plus, an environment that it can actually see you through the web cam. You can download it now at http://www.luxand.com/blink/
Also, it offers additional features such as logs of times your account was logged in, and snapshots from the webcam if someone logs in using any other method. It also claims that it has NO FALSE POSITIVES and NO DELAYS in logging you in. So why not try it out now?
