title: Pulling from BitBucket with private key
body: <p>I have a repository on BitBucket, currently public, but I would like it to be private. The program I'm developing automatically pulls from the repo on close (for the user, not the developer).</p>
  
  <p>Making it private doesn't work however, because my users don't have an account. Is there a way to create some sort of "user key" which I can just pass with the automatic pull? Also, can I restrict it to pulling only? I know that doing something like this isn't super safe, but it's good enough.</p>
  
  <p>I have searched for hours for this, but obviously either for the wrong thing or I overlooked something. I'm also open for better alternatives.</p>
