Log into Facebook with a One-Time Password

Using Facebook on a public computer, or even on a friend's computer, can be risky. Facebook stores a cookie in the browser that enables the user to get into the site without actually logging in. This would make it possible for someone else to easily gain access to your account. Instead of avoiding Facebook entirely, there is a way you can still use it and prevent someone else from being able to get in — by using a one-time password.
