A _user_ is defined as any individual who can log in to Grafana. Each user is associated with a _role_ that includes _permissions_. Permissions determine the tasks a user can perform in the system.
If you have [server administrator]({{< relref "../about-users-and-permissions/#grafana-server-administrators" >}}) permissions in Grafana, you can manage all users for a Grafana instance in the Server Admin section:
If you have [organization administrator]({{< relref "../about-users-and-permissions/#organization-roles" >}}) permissions and _not_ [server administrator]({{< relref "../about-users-and-permissions/#grafana-server-administrators" >}}) permissions, refer to [Manage users in a organization]({{< relref "../manage-org-users/" >}}).
