title: Is this SSH RSA key correctly entered?
body: <p>Related to <a href="https://stackoverflow.com/questions/66487859/error-happens-on-git-when-i-push-with-multiple-github-accounts-on-the-same-compu/66488454?noredirect=1#comment117541253_66488454">this question about SSH public key</a> for using multiple Github accounts, I'm a bit afraid that the SSH public key I registered in Github might be the one I mispasted.
  The format of the text I pasted in the SSH public key form is like this:</p>
  <pre><code>ssh-rsa [Many characters 1]/[Many characters 2]/[Many characters 3]/[Many Characters 4]/[Many characters 5] myUsername@DESKTOP-XXXXXXX
  
  </code></pre>
  <p>I'm afraid that the text above holds the directory name of my computer <code>myUsername@DESKTOP-XXXXXXX</code>
  at the end. Is it correct format of SSH public key?
  I know nothing about SSH but I just felt a bit weird that the security key has the directory name of the user's computer at the end.
  I'm guessing I have to trim the directory name after <code>[Many characters 5]</code>.</p>
