Demo mode is a useful tool for resellers to demonstrate the panel's features without actually allowing anyone enough access to make unauthorized changes in the panel. A user may log in and see all features but cannot make changes.
To enable demo mode, log into DirectAdmin as 'admin', and navigate to the 'Administrator Settings' section of the panel.
You will see the options to enable demo mode for users, resellers, and admins as well as the login details.
Click the check box next to the demo modes you'd like enabled and SAVE.
You should now be able to showcase your DirectAdmin panel via a safe, restricted-access login. :)
