OS X Mountain Lion Password Requirement

Hello,

I currently have my user account on my Macbook Pro set so that I have to enter a password to log in. I would like to change this so I don't have to use a password to log in but I cannot find the settings to change this anywhere. There are multiple places to change the password, but no option that I can find to remove the password requirement. I'm probably just missing something simple but any help is appreciated.
