You can use the Security module in Unified Namespace (UNS) to establish secure access to the message broker by allowing only authorized users to publish or subscribe to messages. It also provides tools to manage and control MQTT client accounts. 
Overview of MQTT Accounts
An MQTT account represents a client connection to the message broker. Each account can:
Be assigned specific permissions (e.g., publish, subscribe, or both).
Be managed (reset passwords, enable/disable accounts).
There are two types of MQTT accounts:
General MQTT Client Accounts: For standard client connections.
Litmus Edge (LE) Client Accounts: These include additional features, such as using a single connection token for streamlined access.
