I found an interesting article today on CNET, regarding an interesting flaw in older account's password storage.
It appears that only the first eight characters of the password are of any relevance, and any characters that follow are irrelevant. What does that mean for us? Well, you should probably give it a try to see if it is affecting your account, as the password you are using may not be as secure as you think. Apparently, it is only affecting older accounts, so generate yourself a fresh password just to be sure.
