Twitter Recommends All Users Change Passwords Due To Bug

A recently discovered bug has prompted Twitter to ask all of its users to change their passwords “out of an abundance of caution.”

Twitter revealed the bug in a blog post today titled “Keeping Your Account Secure.” The company says passwords are masked, however, a bug was discovered “that stored passwords unmasked in an internal log.”

Twitter CTO Parag Agrawal explained in the post that Twitter uses an industry standard fucntion, bcrypt, to replace an actual password with random numbers and letters. This way, Twitter’s systems can validate account credentials without revealing the password.

The bug caused passwords to be “written to an internal log before completing the hashing process,” Agrawal writes. “We found this error ourselves, removed the passwords, and are implementing plans to prevent this bug from happening again.”

“We have fixed the bug, and our investigation shows no indication of breach or misuse by anyone,” the post notes.

Twitter recommends that you change the password both on Twitter, and anywhere else where you use the same password. (As we’ve written before on many occasions, computer users should know to never use the same password for two separate websites.)

Twitter users should act post haste to change their passwords — and when choosing a new password, pick something completely new and unique. Stay away from common phrases. (Don’t pick anything that would have ended up on a Worst Passwords list, for instance.)

In Twitter’s own blog post, it gives the same password advice, including another piece of advice we always give: use a trusted password manager to ensure strong password use. Check out our roundup of the best password managers, and be sure to read our full reviews and comparison articles, as well.
