We recently identified a bug that stored passwords unmasked in an internal log. We have fixed the bug, and our investigation shows no indication of breach or misuse by anyone. “Out of an abundance of caution, we ask that you consider changing your password on all services where you’ve used this password. You can change your Twitter password anytime by going to the password settings page.” Agrawal elaborates the bug as saying that Twitter normally masks user passwords in the course of a state-of-the-art encryption technology called “bcrypt,” which restores the user’s password with a random set of numbers and letters that are stored in Twitter’s system.
