A new program called Blink! works with Windows 7 64-bit and 32-bit operating systems to allow users to authenticate themselves and log in with a webcam. The biometric security app work with multiple users and can create a log of all users who try to log-in. The downside right now is that Blink! only works with the main system log-in in Windows, but doesn’t work to fill in passwords on websites.

You can go to the developer’s website and download the latest version of Blink!.
