The two special groups in Confluence are:
- administrators - these users have permissions to add and administer users, and access the Confluence Admin console.
- users - this is the default group into which all new users are assigned. Permissions defined for this group will be assigned to all new Confluence users.
Your Confluence instance may have other groups, and the names of your default groups may differ if they've been edited by a Confluence admin. See Default Groups and Permissions in Atlassian Cloud.
All users who don't log in when they access Confluence are know as 'anonymous' users. By default, anonymous users don't have access to view or change any content in your Confluence instance, but Confluence admins can assign permissions to this group if it's required.
Overlapping group and user permissions
When a user is assigned more than one permission, the more powerful permission will prevail.
- A user may be assigned a permission specifically to their username. They may also be assigned a permission by belonging to a group, or even several groups.
- The user will then be able to perform all functions assigned to them.
- So if a user is allowed to do something over and above what the group can do, the user will be able to do it. And if the group is allowed to do something over and above the specific permissions granted to the user, the user will still be able to do it.
- If anonymous users are allowed to do something over and above what the user or group can do, the user will be able to do it, (even while logged in).
Unlicensed users from linked applications
If you're using Confluence as a knowledge base for Jira Service Desk, your Jira Service Desk administrator can choose to allow all active users and customers (that is logged in users who do not have a Confluence license) to view specific spaces.
These users have very limited access, and cannot be granted permissions in the same was as an individual or group. However, it's important to note that this permission overrides all existing space permissions, so any logged in Confluence user will also be able to see the space (regardless of their group membership). This is due to the way Confluence inherits permissions.
