​
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: 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.

​
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:
