Facebook one-time passwords

Facebook is enabling a feature that I wanted Gmail to have a long time ago: one-time use passwords. These are passwords that you can only use one time. This is helpful if you're using a not-as-secure computer and are worried that someone might have captured your password (and you don't want others to be able to use your password.) In order to use this, you have to register a mobile phone with your Facebook account, and send a text to Facebook to receive a one-time password (that must be used within 20 mins.)

From the Facebook blog:

First, we're launching one-time passwords to make it safer to use public computers in places like hotels, cafes or airports. If you have any concerns about security of the computer you're using while accessing Facebook, we can text you a one-time password to use instead of your regular password.

Simply text "otp" to 32665 on your mobile phone (U.S. only), and you'll immediately receive a password that can be used only once and expires in 20 minutes. In order to access this feature, you'll need a mobile phone number in your account. We're rolling this out gradually, and it should be available to everyone in the coming weeks.

I try not to use other computers/devices to access personal information unless absolutely necessary. And nowadays, with all the smartphones out there, you don't really need to use someone else's computer. But it's nice to know there's this feature for passwords.
