title: What is a 'temporary clone token' (in GitHub)
body: <p>I'm using <a href="https://classroom.github.com/" rel="nofollow noreferrer">GitHub Classroom</a> to manage student assignments through GitHub.  The basic workflow is that I create an assignment (including a starter repo), the students fork the repo on GitHub, clone it to their computers, then commit/push their changes back to GitHub.</p>
  
  <p>I'd like to modify their repos and push my changes (technically I just want to add a file with feedback, not change their code, but that's neither here nor there).</p>
  
  <p>When I try to push the changes back to GitHub I get the following error:</p>
  
  <pre><code>remote: Temporary clone tokens are read-only.
  fatal: unable to access 'https://github.com/2019-BIT-142/bit-142-lesson-10-StudentsName.git/': The requested URL returned error: 403
  </code></pre>
  
  <p>What is a 'temporary clone token'?  Why am I getting a 403 (forbidden) response?  </p>
  
  <p>I even wiped out my GitHub credentials (I'm using the Windows Credential Manager) and it's not even asking me for my username / password, so I'm assuming it's a problem with the 'clone token' itself, not my account.</p>
