I don't want to remove the option - I want a password request on it, you 
know like "username:" followed by "password:". I generally do not like 
the idea of my computer being open to access by anyone who gets their 
hands on it. So I figured that if I booted into "rescue" (I hope we mean 
the same) mode and set a password I would be asked for that next time. 
But wanted to make sure I don't get headaches from my normal login.
