Right after the installation, Plesk uses a trial license key. To get a paid license key, go to the Plesk online store (shop.plesk.com), select, and then purchase a necessary license key.

Once you purchase the key, you will receive an activation email with your activation code.

Pour installer une clé de licence à l’aide d’un code d’activation :

  1. Go to Tools & Settings > License Management (under « Plesk ») and click Install Key.
  2. Enter the code you received in the email to the « Enter an activation code » field and click OK.
