The following article will demonstrate how to adjust an admin user's permissions. Most parts of the admin will require a level of permission to access. You can restrict access by removing permissions for the user you'd like to limit access to.
Updating Permissions
Log in to your admin account.
Use the email and username you have chosen or assigned by your Leap representative. If you have forgotten your password, select "Forgot Your Password" at the bottom.
Once you have successfully logged in, hover over the Settings button from the menu bar at the top of the screen, then select All Users.

Select the user you would like to alter permissions for by clicking on their name or email address.

Scroll down to view the user's General & Extended permissions, you can edit their View, Add, Edit or Delete permissions for various sections of the admin.
The extended permissions can be used to grant access to other admin panel features usually reserved for the master user. Once you've finished editing their permissions, click Save Permissions to commit the changes.

By default, main account holders have all the general permissions, so it will only show the options and only the extended permissions.
