Moving to enhance online security, Facebook on Tuesday said that it will soon offer users the ability to receive one-time passwords on their mobile phones and that it has already enabled the ability to sign out of Facebook remotely.
"[W]e're launching one-time passwords to make it safer to use public computers in places like hotels, cafes or airports," said Facebook product manager Jake Brill in a blog post. "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."
