Passwords on the way out?

Via Mitch, I saw this article in the New York Times about replacing passwords as a method for accessing private accounts online. Id be interested in this for sure, though it looks (at first glance) like the big limitation would be for those who want to access their online accounts from multiple machines. On the other hand, I often find myself considering that kind of accessibility a necessity, but then I realize that I almost never access my email or any other online account from any machine other than my own laptop, so a hardware-specific option wouldnt be that bad. In the meantime, Ill continue to maintain my file of 54 different 12-character passwords and try to update them every few months… sweet….
