title: How can I push to my fork from a clone of the original repo?
body: <p>I created a fork (let's call it <code>myrepo</code>) of another repository (let's call it <code>orirepo</code>) on GitHub. Later, I cloned <code>orirepo</code>.</p>
  
  <pre><code>git clone https://github.com/original/orirepo.git
  </code></pre>
  
  <p>I modified about 20 files, then I staged my change and made a commit</p>
  
  <pre><code>git add
  git commit
  </code></pre>
  
  <p>However, when I tried to push</p>
  
  <pre><code>git push
  </code></pre>
  
  <p>I got this error:</p>
  
  <pre><code>remote: Permission to original/orirepo.git denied to mylogin.
  fatal: unable to access 'https://github.com/original/orirepo.git/': The requested URL returned error: 403
  </code></pre>
  
  <p>I know I made a mistake: I should have cloned my fork rather than <code>orirepo</code>, but it's too late for that now.
  How could I push to my fork rather than to <code>origin/orirepo</code>, which I don't have write access to?</p>
