Depending on the sort of work you do, this may or may not be new to you, but it must be relatively new, and it's most definitely cool. I'm told that more and more companies are using things like this to allow key individuals (like their attorneys) access to confidential resources. In fact, RSA Security says that more than 15 million people are using their SecureID system for two-factor (something they know and something they have) hardware authentication. Basically you get a "token," a key fob with an LCD screen. The screen shows a number with 6 digits. The number changes every 60 seconds or so. To gain access, you have to enter that specific code and your personal password. The code only works at that moment in time and only with the second factor as well. Naturally, details are confidential, but I encountered one of these today and was impressed with the system since I hadn't seen it before.
