Twitter warns:

Change passwords

Twitter is advising all users to change their passwords.

The San Francisco company said Thursday that it recently discovered a bug that stored passwords in an internal log in an unprotected form. Twitter says there’s no indication that there was a breach or that any of the passwords were misused. But as a precaution, Twitter recommends users consider changing the passwords they use to log onto Twitter. They should also change that password if they used it for any other services.
