​
Why Use User Management?

You need to control who can connect to your broker—add users, set passwords, and manage access. The User Management in the Coreflux HUB lets you create, edit, and delete users without editing configuration files or using command-line tools.

​
When to Use It

  • Adding users — Create new users for devices, applications, or operators
  • Updating credentials — Change passwords
  • Managing permissions — Control which features each user can access
  • Removing access — Delete users who no longer need broker access
For topic-level and group-based access control with LoT Rules, see RBAC with LoT Rules.

​
Accessing User Management

In the HUB top navigation, select System, then User Management. The user accounts table shows all configured users with their permissions.

​
User Permissions

Each user has permission flags. The HUB table exposes three toggles that map to broker flags: Toggle permissions on or off for each user. The root user has special permissions that cannot be fully modified.

​
Groups

Users can belong to named groups used by LoT Rules (USER IN GROUP) and Visu panel sharing. Manage groups with MQTT commands (-addUserToGroup, -removeUserFromGroup, -listUserGroups) — see Broker Commands and RBAC.

​
Creating a User

  1. Click the + button in the top-right corner.
  2. The Add New User modal opens.

  2. Click Add User. The user is created with default permissions and can now connect to the broker.

​
Editing a User

Toggle permission switches directly in the user table to modify access. When you change a permission, the user row shows a Modified badge and action buttons appear:
