The rabbitmqctl command with the add_user option can be used to create a user. In this example, john.doe will be created with password itsasecret.

rabbitmqctl add_user john.doe itsasecret

If the user account is successfully created, something like this should be returned.

Creating user "john.doe"

Typically, you would next update the users account with a tag and grant the user access to a virtual host.
