With that in mind, think about what would go into a proper risk analysis versus cost/benefit analysis of multi-factor authentication. Your risk analysis would look at the probability of threats stealing your credentials, and the impact a compromise would have. Now map out some scenarios with likely costs for handling breaches cause by stolen passwords. What's cheaper? The costs of implementing a multi-factor solution, or the cost of a breach?
It seems like a no-brainer to me since barriers to entry for multi-factor authentication aren't nearly as steep as they once were. The Yubikey is a great example. It is inexpensive, has numerous ways to integrate it into common environments, and whether you are using the OTP or static password functionality, requiring it along with a user name and password becomes a huge hurdle for an attacker to overcome.
That reminds me...I need to change a few passwords that are about to expire. When will the madness end?
