Description

When using public dashboards and direct data-sources, all direct data-sources' passwords are exposed despite not being used in dashboards. No passwords of proxied data-sources are exposed. We encourage all direct data-sources to be converted to proxied data-sources as far as possible to improve your deployments' security.
