Multi-factor Authentication

Multi-factor authentication was first discussed extensively on Security Now podcast, Episode 90. In Episode 101, during the reader-mail section, the Paypal Security key was mentioned, and was thoroughly discussed with Michael Vergara, PayPal's Director of Account Protections, in Episode 103.

I've gotten a Paypal security key, and I'm studying the specification as outlined in the OpenID Book by Rafeeq Ur Rehman.

I think it's an excellent idea and encourage all who read to follow-up and implement personally. The proliferation of OpenID could really help reduce the confusion of multiple passwords and login IDs that may of us have, AND, reduce the number of weak passwords we use.
