AT THE END of last month, Facebook made a bombshell disclosure: As many as 90 million of its users may have had their so-called access tokens—which keep you logged into your account, so you don’t have to sign in every time—stolen by hackers. Friday, the company put the actual number at 30 million. Here’s how to see if you were one of them, and if so, what the hackers got from your account.
There might understandably be some confusion around the matter; a few weeks ago, Facebook logged out 90 million of its users out of an abundance of caution, making them reset their passwords and negating the access token hack. Over the next few days, Facebook will insert a customized message into the News Feeds of the 30 million people whose accounts were actually impacted, based on the extent of the damage.Original Source
