A role in Drupal is a collection of associated permissions for either a website function or a level of website access, administrators can assign to user accounts.
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:
Anonymous: Site visitors not signed in to your website.
Authenticated: Signed-in site visitors who are registered users on your website.
Administrator: Signed-in administrative superusers of your website. This role is assigned every permission for every enabled module. Administrators have full access to all available features on your website. You should only assign the Administrator role to users whom you trust.
Note
Drupal’s permissions and roles aren’t the same as Acquia’s Teams and permissions.
