You know how email accounts make you log in with your address and your password? Why should they need both? Can't they do it with just your password?
Well, I guess the problem with that would be that then everyone would have to have different passwords, and what if someone else also wanted "fuzziekittiekats" to be their password? You'd accidentally log in to their email, and they might log in to yours and then you would get confused, and they would get confused, and all hell would break loose.
So, the moral of the story is "fuzziekittiekats" is not a secure password.
