Twitter is strongly recommending that all 330 million of its users reset their password after they found a bug had exposed all passwords in plain text.
Twitter has investigated the bug and confirmed that there is no evidence of any breach or misuse of any of the passwords. However, they are urging all users to reset their passwords as a precautionary measure.
The passwords were only exposed internally, so this is a good move by Twitter to go public straight away.
So stop reading this and go change your passwords….you are welcome
