Version 2 of the XML Editor has two different types of login: ADMIN and USER
Logging in as the ADMIN will give you full access to use the editor, but also to configure the editor itself by right-clicking on the background of the top menu or by right-clicking on individual buttons of the menu. To see details of each of the actions available, see the "Admin Menu Options" and "Admin Button Options" sections of this userguide.

Logging in as a USER will disable all of the right-click editing options, but will still allow the USER to use the XML Editor as it has been set up. A good example of using the Admin and User passwords is a developer using the ADMIN login to set up the color, tabs, and interfaces of the editor, then giving their client (who might not be as saavy) the USER name and password to edit the properties of their XML files.
