Hello @neild , in this case, I think you need to set access control to the "dashboard" resource within your application. If you pass the URL generated by Metabase directly, it will be public, with access by anyone who has the URL. Another way, perhaps, would be to use the feature to "embed" the dashboard in your application. But remember, regardless of the form of sharing, if you want security, you have to enforce access control.
