Protect the Swarm admin console with username/ password

QUESTION: How can I lock down the Swarm Admin Console so that even read-only visibility has a username/ password requirement?
ANSWER: To do so, configure a non-default user in the operators line in your node.cfg. In that line, configure the users that need visibility to the console.

Example:

operators = {'snmp':'public', 'testuser':'testpass' }
