title: Do I need multiple developer certificates in order to join multiple developer programs?
body: <p>It's hard to fully understand all this certificate stuff for IOS development and it's implications.</p>
  
  <p>One piece of info I can not find in the docs or via google:  In order to join multiple developer programs (when working on software for different clients), should I create a unique developer certificate for each, or can I use the one I already have?</p>
  
  <p>Is there an advantage/disadvantage in either way?</p>
