Open

The open access control rule does nothing.

It is used if you are want to normally allow access to an endpoint, but want to also allow some additional (usually elevated) access control methods.

For example…

"specialwriter": [[{
	    "type": "open",
            "demote": "reader"
	  }]],
          [{
	    "type": "whitelist",
	    "list": ["127.0.0.1","localhost"],
	    "elevate": "editor"
	  }]

In this example, most users - even people who can normally write - will be demoted to being a reader, but users running on the local system are automatically elevated to 'editor' without the need to sign in.
