Facebook Says Millions of Passwords Were Visible Internally

Facebook Inc. disclosed a flaw on its social network that made passwords of hundreds of millions of users visible to employees and said the issue has now been fixed.

During a security review in January, Facebook found that the passwords were stored in a readable format, against its security procedures, but that they were never visible to anyone outside of the company. Most of the accounts affected were using Facebook Lite, a version of the app designed for emerging markets. The company said it hasn’t found evidence this access was abused.
