User One (User 1) is a special user account in Drupal CMS that is used to manage the system. It is the first user account created when Drupal is installed and is the most powerful user account in the system. User 1 has full administrative privileges and can access all areas of the system, including the administrative interface. User 1 is also the only user account that can access the database directly.
User 1 is a critical account in Drupal and should be protected with a strong password. It is important to note that User 1 is not the same as the anonymous user, which is the user account used by visitors who are not logged in. User 1 is also not the same as the authenticated user, which is the user account used by visitors who are logged in.
User 1 is a powerful account and should be used with caution. It is important to remember that any changes made by User 1 will affect the entire system, so it is important to be aware of the potential consequences of any changes made.
