title: git pull with access token, git push with username / password
body: <p>I've got a problem with git push. Here are many threads regarding this issue, but none of them fit to my problem. </p>
  
  <p>The company I work for, has it's own gitlab. Policy is only https, no ssh is allowed. For cloning and pulling, an access token is required. Pushing only with username/password. Don't ask me about the underlaying reason. Unfortunately I don't know it. </p>
  
  <p>Error message is: </p>
  
  <pre><code>$ git push
  fatal: unable to access 'https://&lt;username&gt;:&lt;AccessToken&gt;@&lt;domain&gt;/&lt;owner&gt;/&lt;reponame&gt;.git/': The requested URL returned error: 403
  </code></pre>
  
  <p>At least I alread was able to clone a repo, but I'm failing to push the changed content respectively. Ubuntu 18.04 is running on my laptop. 
  What do I need to do to solve my issue? </p>
