title: How can I prevent users from using my AppId and JavaScript key to generate new users?
body: <p>I am building a website with a Parse backend. So I'm building register/login right now, and am thinking that users can take the AppId and Javascript key and write their own javascript to register users on their own.</p>
  
  <p>How can I prevent this from happening, is there a way to restrict the IPs where javascript Parse can run?</p>
