-If {security} is enabled, Kibana has a built-in `kibana_dashboard_only_user` 
-role that grants read-only access to {kib}. This role is sufficient
-for most use cases.  However, if your setup requires a custom {kib} index, you can create
-your own roles and tag them as *Dashboard only mode*.
-
-Go to *Management > Kibana > Advanced Settings* and search for *Dashboard*. By default 
-`xpackDashboardMode:roles` is set to `kibana_dashboard_only_user`. 
-Here you can add as many roles as you like.

-preconfigured with read-only permissions to {kib}.
+deprecated[7.4.0, Using the `kibana_dashboard_only_user` role is deprecated. Use <<kibana-feature-privileges,feature privileges>> instead.]
 
-IMPORTANT: You must also assign roles that grant the user appropriate access to the data indices.
-For information on roles and privileges, see {xpack-ref}/authorization.html[User Authorization].
+In dashboard-only mode, users have access to only the *Dashboard* app. 
+Users can view and filter the dashboards, but cannot create, edit, or delete
+them. This enables you to:
 
-Users assigned this role are only able to see the Dashboard app in the navigation
-pane. When users open a dashboard, they will have a limited visual experience. 
-All edit and create controls are hidden. 
+* Show off your dashboards without giving users access to all of {kib}
+
+* Share your {kib} dashboards without the risk of users accidentally 
+editing or deleting them
+
+Dashboard-only mode pairs well with fullscreen mode.
+You can share your dashboard with the team responsible 
+for showing the dashboard on a big-screen monitor, and not worry about it being modified.
