"/setting/user/<userid>/npaccount/accountid" will be your psn id
"/setting/user/<userid>/npaccount/loginid" will be your email address
"/setting/user/<userid>/npaccount/password" will be your password
people say you don't need to edit the part about your birthday, but those 3 should be all you need to change.
