Facebook on Thursday said millions of Instagram user passwords were exposed to employees in a searchable format in an internal database.

The announcement came in an update to a blog post that was published last month after the company disclosed millions of Facebook user passwords were exposed to employees. The blog post originally said thousands of Instagram passwords were exposed. Cybersecurity journalist Brian Krebs reported in March that up to 600 million Facebook passwords were exposed.
