title: How to put a site into maintenance mode while still allowing only me to access?
body: <p>I am about to upgrade my whole site and I am looking for a way to do the maintenance process, but still allowing me to access.</p>
  <p>I am thinking of using htaccess. However, that only redirects users accessing for example, index.php to maintenance.php, right? If a user accesses dashboard.php, there will be no redirection.</p>
  <p>During the maintenance, I do need to access index.php (ONLY ME).</p>
