You can configure MQTT plugin to not perform authentication as authentication
is optional in MQTT:
http://www.rabbitmq.com/mqtt.html

If you ask me, this is a terrible MQTT feature (and in fact
I know that some MQTT-based services reject unauthenticated clients).
But if you use default_user and default_pass, you do not need to provide
any credentials. That's why default_user/default_pass are there.

Again, this is pretty clearly documented in http://www.rabbitmq.com/mqtt.html.
