PINs, passwords, secure entry systems; just about everything you access these days needs some form of passive authentication code. Heck, even that Wi-Fi router in your basement uses a mega 63-character password for enabling secure access. Before you know it, you’ll even need a password just to go to bed at night.
More often than not, these security code systems require you to enter a lengthy 8- or more digit alphanumeric sequence. And creating powerful, unique, protective passwords can be a tough challenge for most people. What you need is some sort of portable, automatic, press-the-button-and-read-the-password device. Pass Key is an attempt at satisfying this requirement.
