Facebook Left 'Hundreds of Millions' of Passwords Exposed to Employees

Facebook Inc. said that it had left “hundreds of millions” of users’ passwords exposed in plain text, potentially visible to the company’s employees, marking another major privacy and security headache for a tech giant already under fire for mishandling people’s personal information. Facebook said it believed the passwords were not visible to anyone outside the company, and had no evidence that its employees “internally abused or improperly accessed them” — but said it would notify users of its namesake social network, and of its photo-sharing site Instagram, that they had been affected.
