An attack on Facebook discovered earlier this week exposed information on nearly 50 million of the social network's users, the company announced Friday. The attackers exploited a feature called "View as" that lets users see their Facebook page the way someone else would. More than 90 million users were forcibly logged out of their accounts by Facebook and had to log back in on Friday for security reasons. Users do not need to take any additional security precautions or reset their passwords, said Facebook. Facebook reset all 50 million tokens, as well as tokens for an additional 40 million people who had used the "View as" feature in the past year as a "precautionary step."
