Facebook admitted today to storing the passwords of millions of Instagram users in plaintext format in internal server logs.
The announcement came as an update to an
incident from last month when the company admitted to storing plaintext passwords
for hundreds of millions of Facebook Lite users, tens of millions of Facebook users, and tens of thousands of Instagram accounts.
"We discovered additional logs of Instagram passwords being stored in a readable format,"
the company said in an update published today.
"We now estimate that this issue impacted millions of Instagram users. We will be notifying these users as we did the others."
Facebook said that its investigation revealed that none of these plaintext passwords were abused by employees.
