The currently supported auth related settings are:
Scopes can be associated with a separate registry. This allows you to seamlessly use a mix of packages from the primary npm registry and one or more private registries, such as GitHub Packages or the open source Verdaccio project.
In order to scope auth tokens, they must be prefixed by a URI fragment. If the credential is meant for any request to a registry on a single host, the scope may look like //registry.npmjs.org/:. If it must be scoped to a specific path on the host that path may also be provided, such as //my-custom-registry.org/unique/path:.
