Hi @sbcsuman,
This is our RabbitMQ documentation:
https://docs.bitnami.com/virtual-machine/infrastructure/rabbitmq/get-started/first-steps/
As you can see, the default user is user
and the password can be obtained with the command below:
sudo cat /opt/bitnami/var/log/pre-start.log | grep "application password"
If you want to create another user, you should run:
sudo /opt/bitnami/rabbitmq/sbin/rabbitmqctl add_user test test
sudo /opt/bitnami/rabbitmq/sbin/rabbitmqctl set_user_tags test administrator
I hope it helps
