There are several roles you can assign to a user based upon the level of access needed.
In addition to the levels of access, there are additional tools to help manage multi-user access in the system.
Audit trails are recorded whenever a user interacts with the system. These allow you to monitor when a user has interacted with the system and track any changes made by a particular user.
Comments allow users to document particular information related to specific devices, errors, or issues during a specific time period.
