title: Error Pushing my Repository to Github
body: <p>I typed into the terminal:</p>
  
  <pre><code>Parkers-MacBook-Pro:first_app ppreyer$ git push -u origin master
  Username: 
  Password:
  </code></pre>
  
  <p>And I get this error:</p>
  
  <pre><code>error: The requested URL returned error: 403 while accessing https://github.com/ppreyer/first_app.git/info/refs
  
  fatal: HTTP request failed
  </code></pre>
  
  <p>I'm guessing it has something to do with my username and password but I feel like I'm entering in the right information. Is there a way to figure out what my username and password are?</p>
