This isn't the only recent security update. Back in October, the company announced one-time logins and remote logouts as new ways of staying ahead of the bad guys. If you are using a public computer, for example, and don't want to reveal your login to it -- or the people milling about -- for fear of a security breach, text "otp" to 32665 from a U.S. mobile phone. You'll receive a one-time-use password that expires in 20 minutes.
If you've already signed in from another computer, you can check to see if you remembered to properly log out. In fact, you can check to make sure you recognize all the recent logins to your account. Go to the Account Settings page, look under Security, and see what computers and their locations (based on IP address) are currently logged into your Facebook account. You can sign out of any of them from this panel and opt to be alerted by email or text whenever your account is accessed.
But given all the celebrity hackings, I'm starting to wonder if having your Facebook page hacked is now a sign of social status. Maybe we've reached the point where you aren't somebody till somebody has hacked your network.
