title: HubFlow: certain HubFlow commands prompt me for my GitHub credentials multiple times. Is there a way around this?
body: <p>I am currently learning the <a href="http://datasift.github.com/gitflow/GitFlowForGitHub.html" rel="nofollow">HubFlow</a> way of managing versioning and workflow using Git and GitHub.</p>
  
  <p>I created this <a href="https://github.com/simkimsia/learnhubflow" rel="nofollow">dummy repository</a> to get some hands-on experience.</p>
  
  <p>I have tried certain commands like</p>
  
  <pre><code>git hf update
  </code></pre>
  
  <p>I get prompted for my GitHub credentials multiple times.</p>
  
  <p>Here is an example:</p>
  
  <pre><code>macair:learnhubflow simkimsia$ git hf update
  Fetching origin
  Already on 'master'
  From https://github.com/simkimsia/learnhubflow
   * branch            master     -&gt; FETCH_HEAD
  Already up-to-date.
  Username: 
  Password: 
  Everything up-to-date
  Switched to branch 'develop'
  Your branch is behind 'origin/develop' by 2 commits, and can be fast-forwarded.

  <p><strong>Is there a way for me to simply supply the GitHub credentials just once each time I used a HubFlow command?</strong></p>
