At the end of September, 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. Facebook will insert a customised message into your News Feeds if your account affected.
If you don’t want to wait for the message to hit your News Feed to find out if you’re okay, go ahead and see if you were among those hit at Facebook Help Centre.
