Navigating to User Management in the Coreflux HUB by selecting System in the top navigation and clicking User Management

​
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

​
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 three permission categories, controlled by toggles:
PermissionDescription
Full AccessFull administrative access to broker configuration and asset management
User ManagementPermission to create, edit, and delete other users
Log ManagementAccess to broker logs, trace logs, and log export
Toggle permissions on or off for each user. The root user has special permissions that cannot be fully modified.

​
Creating a User

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

  1. Enter a username and password (with confirmation).
  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:

The header bar shows badges for modified users and System Updated status when the broker configuration changes while you are editing.

​
