title: Cannot push to my clones repository
body: <p>I have seen a lot of questions about this, but a lot of them are outdated and the rest refer to different peculiarities of this same issue. I am sorry if I could not spot a similar question in case I am creating a duplicate.</p>
  
  <p>I have just cloned a repository that I created. </p>
  
  <pre><code>git clone https://github.com/mygituser/myproj.git
  </code></pre>
  
  <p>I can <code>git add</code> and <code>git commit</code>. But when I go <code>git push origin master</code> authentication fails like this:</p>
  
  <pre><code>[user@mach myproj]$ git push origin master
  Username for 'https://github.com': mygituser
  Password for 'https://mygituser@github.com': 
  remote: Invalid username or password.
  fatal: Authentication failed for 'https://github.com/mygituser/myproj.git/'
  </code></pre>
  
  <p>These are my origins:</p>
  
  <pre><code>[user@mach myproj]$ git remote -v
  origin  https://github.com/mygituser/myproj.git (fetch)
  origin  https://github.com/mygituser/myproj.git (push)
  </code></pre>
  
  <p>My Git user is <code>mygituser</code>, I also set my username and password:</p>
  
  <pre><code>git config --global user.name "mygituser"
  git config --global user.email "XXX@gmail.com"
  </code></pre>
  
  <p>What am I doing wrong?</p>
