The hacking of user credentials has been recently faced by some of the major IT companies like LinkedIn and Microsoft India. You, as a service user, have no control on them, but another stand is yours. That's choosing a strong and a less common password, difficult to guess. This will protect your account from random login attempt by some bad guys. It may be one of your friend trying a combination he saw you typing somewhere.

I am not talking here about how you can have a strong password, and do's and don't for that. But populating a list of some common, or rather say a worst list of passwords most of the users have. These are easy to remember, and also easy to guess.
