OOPS: Twitter Tells Users To Change Passwords After Discovering Glitch.

The company says it fixed the bug and there is no indication of a breach or misuse.

Still, it’s urging its 330 million users to change their passwords as a precaution.

The issue appeared through a bug in Twitter’s password hashing. It’s a standard security practice for companies to encrypt passwords to store on its internal servers. So if your password is “12345” — which we highly recommend against — it wouldn’t show up on the website’s database as “12345,” but rather a random mix of numbers and letters representing each character.

Twitter said it stored encrypted passwords using a hashing algorithm called bcrypt. But the social network had stored the password in plain-text before it was encrypted. Twitter said this happened because of a bug. The company did not respond to a request for comment to clarify what the bug was.

If you’re still on Twitter, here are instructions for changing your password.
