Google announces support for USB second factor authentication
Google has been offering two-factor authentication for its services for some time, but this week they announced that users are going to have a new option: a physical second factor, in the form of a USB key. It's optional, of course, but if you opt in you'll be able to insert a USB key into your computer's USB port. You'll then be prompted by Chrome to tap a button, to verify that the logon site is the real thing.
