Facebook confirmed Thursday that hundreds of millions of user passwords were being stored in a “readable format” within its servers, accessible to internal Facebook employees — including millions more Instagram users than previously thought. Affected users will be notified, Facebook said, so they can change those passwords.

“We now estimate that this issue impacted millions of Instagram users,” Facebook wrote. “We will be notifying these users as we did the others. Our investigation has determined that these stored passwords were not internally abused or improperly accessed.”

Facebook is the Samsung of social media. They just can’t stop shooting themselves in the feet. Unlike Samsung, their screw ups can create a lot more damage.
