title: Switch between user identities in one Git on one computer
body: <p>I have <strong>ONE</strong> repository on <strong>GitHub</strong>, let's call it <code>Repo-1</code>.</p>
  
  <p>I want to first access that repository as a <strong>default Git user</strong>.</p>
  
  <p>Let's call that user <code>User-1</code>.</p>
  
  <p>I created <strong>SSH keypair</strong>, everything fine, <strong>works nice</strong>.</p>
  
  <hr>
  
  <p>I made <strong>ANOTHER</strong> repository on <strong>GitHub</strong>, let's call it <code>Repo-2</code>.</p>
  
  <p>I <strong>didn't make any changes in local Git</strong>, on my laptop. No configurational changes, nothing.</p>
  
  <p>Now - I want to <strong>clone</strong> from <code>Repo-1</code> as the <code>User-2</code> (but <strong>from the same laptop</strong>).</p>
  
  <p>First of all: is this at all possible to do?</p>
  
  <p>Can local Git on one single laptop switch between "user accounts" and present itself as <code>User-2</code>? And then, from THAT identity, clone from Repo-1, make some change, and then push to <code>Repo-1</code>?</p>
  
  <p>If possible, how do I do that?</p>
