Twitter advised more than 330 million users to change their passwords after discovering an internal storage bug, according to a blog post by the company on Thursday. The bug, which was promptly fixed by the company, resulted in passwords being stored unmasked in an internal log. Twitter has stated that following an investigation, there is no indication of breach or misuse.

In the blog post by Twitter, the company shared exactly how the bug had compromised password encryption:

“We mask passwords through a process called hashing using a function known as bcrypt, which replaces the actual password with a random set of numbers and letters that are stored in Twitter’s system. This allows our systems to validate your account credentials without revealing your password. This is an industry standard.” “Due to a bug, passwords were written to an internal log before completing the hashing process. We found this error ourselves, removed the passwords, and are implementing plans to prevent this bug from happening again.”

We recently found a bug that stored passwords unmasked in an internal log. We fixed the bug and have no indication of a breach or misuse by anyone. As a precaution, consider changing your password on all services where you’ve used this password. https://t.co/RyEDvQOTaZ — Twitter Support (@TwitterSupport) May 3, 2018
