Not sure what exactly you mean wrt NoAuth DBs, but having a simple on-connect password would be an improvement to all those databases.
Things like Elasticsearch not having even a basic password (esp since it's HTTP so it's trivial) is simply silly. And it's probably not a good idea to support no-auth connections at all - if it's really a hassle, just set the user/pass to the host name.
