User authentication reference
Enabling user authentication provides you more control over your AWS Elemental systems. Authentication helps secure your nodes while also allowing you to do the following:
Track node activity on a per-user basis.
Limit accidental access to a node by allowing distinct login credentials for each node. This way, an operator with access to multiple nodes must enter the credentials for a specific node prior to sending any commands.
Whether or not you enable authentication, we recommend that all of your nodes are installed behind a customer firewall or on a private network.
The following sections provide more information about user authentication.
