title: Git push requires username and password
body: <p>I cloned a Git repository from my GitHub account to my PC.</p>
  
  <p>I want to work with both my PC and laptop, but with one GitHub account.</p>
  
  <p>When I try to push to or pull from GitHub using my PC, it requires a username and password, but not when I'm using the laptop!</p>
  
  <p>I don't want to type my username and password every time I interact with <code>origin</code>. What am I missing here?</p>
