For example, assigning an account to the Administrator role on your Drupal website gives that user complete access to your website. For comparison, assigning an account to the Anonymous role only grants the user limited access to your website.
To manage user roles on your Drupal website, sign in to your Drupal website as an administrator, go to People > Permissions, and then click Roles.
By default, basic Drupal websites (without any extra changes made by a distribution) include three standard roles:
