Most Common Passwords and PINs You Should Avoid

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.
