“Millions” of Instagram users had their passwords stored in unencrypted form on internal servers, Facebook said Thursday, raising its original estimate of tens of thousands.
“We discovered additional logs of Instagram passwords being stored in a readable format. We now estimate that this issue impacted millions of Instagram users,” Facebook said in a blog post.
“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,” the social network said.
Facebook, Instagram’s parent company, revealed last month that the unencrypted passwords of hundreds of millions of users had been stored, putting the number of Instagram users affected in the tens of thousands.
