# User Group Management
In the CaSS authoring environment, user groups allow for multiple users to assume a single shared 'identity'. Members of a group are granted access to any CaSS object that the group has been explicitly assigned.
Subgroups can be created within Groups to further organize and define access to CaSS objects for multiple users.
# Accessing the CAT User Group Manager
Important: To access the CAT user group manager, you must be logged into the CAT application.
The CAT user group manager can be accessed at any time by selecting the users and groups icon on the lower left corner of the navigation menu.
CAT User Group Manager - Navigation Menu - Users and Groups
The My User Groups list contains options for creating a new group, viewing group members, and accessing existing groups.
To view a list of all group members, click on Member List under My User Groups. This only lists users who are already within a group.
# Creating a New User Group
To create a new group, click on the create new group button under My User Groups.
A new group is created with a default name and description.
Note
There may be noticeable processing time when creating a new group. CAT user groups are assigned identity keys that must be generated at creation time. This process may take several seconds.
# Creating a New Sub-Group
To add a sub-group to a currently open group, click on the add sub-group button under Group actions. Sub-groups can be created within Groups to further organize and define access to CaSS objects for multiple users.
A new sub-group is created with a default name and description. The path of the group and the listing under My User Groups indicate the parent of the sub-group.
The actions for managing users and editing groups apply to sub-groups as well.
# Managing a User Group
To access existing groups in the current CAT instance, click on the group name under My User Groups to the left of the Group Details.
Group Details show the name, description, and a list of members within the group.
Click on the edit icon next to the name and description to edit either of these properties. When you are done editing, click "done editing" to save changes.
