title: How to remove cached credentials from Git?
body: <p>I ran:</p>
  <pre><code>$ git config credential.helper store
  </code></pre>
  <p>And then:</p>
  <pre><code>$ git push origin master
  </code></pre>
  <p>After pushing, I entered my credentials and they were saved.
  <br>I read that they are stored in plaintext, and so now I want to remove my credentials from being saved and entered by default.</p>
  <p>How can I do this?</p>
