If you are on Twitter you have also had the message: due to a bug in the system, the unencrypted passwords of all users have been stored in an internal log. That file could therefore only be viewed by employees of Twitter and as far as the company has been able to ascertain, there has been no leak. The ability to view those passwords is no longer there, but to be on the safe side, the social media site warns that you would be best off changing the password you use for Twitter in all places.
Fair? I don’t think it’s worth it. The only way this poses a real threat to people who are unfamiliar is if there are employees of Twitter who have stolen a complete log file and plan to sell it to the hackest bidder. That chance is extremely small and although it is to Twitter’s credit that they still issue a warning while that is not necessary, you do not have to adjust everything everywhere.
If, on the other hand, you were already on the weak side of the passwords, this might be a good excuse to change them. But yes, that all goes from your Twitter time. If you’re still on it, of course, if you’ve ever had an account and used the password for it on other services , then this applies to you too, so make your decision and change those passwords. Or not.
