# Users Engine usually integrates with an external directory system (such as Active Directory) for authentication. The Users Section lists all users who have signed in, their level of access and a History (log) of the Systems which were accessed (controlled from an Interface or viewed in Backoffice). ## Permissions When first logging on, a user will have no permissions assigned and will be denied access to Backoffice. A System Administrator should then look up the User from the list in the User’s Section of Backoffice and set their permissions: * Tech Support: Have access to view Backoffice and all objects but cannot create or edit Systems and Devices. * System Admin: Full write access to all objects --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
