Username/Password Authentification [Question]

[Alex]

Simple question.

A bit confused :)

MQTT Clients like PAHO MQTT client require username and password authentication when connecting to a broker.

My questions are:

For what purpose does the client provide the username and password?
Does the client sign up at first login?
Who provides the username and password?
Or should I randomly generate 2 strings as the username and password for each client?

Hi Alex, 

Authentication is for security and you can have a single password for all your clients or have unique passwords for each client. The Broker you are running should be enabled for authentication and should be pre configured with a list of usernames and passwords.

Your client should be configured with any one of the username and password combination configured in the broker. 

Heres how we do it https://www.bevywise.com/blog/security-enhanced-with-multiple-authentication-mqttroute/

You can check the corresponding functionality in the broker you are using.
