Facebook is introducing two new measures to beef up security: expanding HTTPS connections as an all-the-time option and using social captchas to authenticate users who have lost passwords. Let's take these one at a time. The social captcha feature is pretty clever. It will replace regular captchas (those slightly warped letters you are asked to re-enter to prove you are human) with a picture of one of your friends. You will need to identify the person to authenticate yourself when you are trying to retrieve a lost password or Facebook detects suspicious login activity on your account. You do know what all your "friends" look like, don't you?
