title: Drupal 8 : How to stop drupal stocking sessions?
body: <p>I created a module to authenticate users thanks to a card and I need to check if they can access the website. </p>
  
  <p>The problem is with the way Drupal manages sessions. It stocks every sessions in the database and restores it, so the user is automatically logged in, this causes the user to not go through the checking process.</p>
  
  <p>Is it possible to stop stocking the sessions in the database ?</p>
