Okay, but that does not answer my question. How would I protect my auth tokens in plain-text, client-side Javascript code without an auth server? Do you provide such an auth server? I only see end-user login which is pretty cool, but usually there are portions of a website which can be seen without the end-user being logged in. In the scenario where the end-user is not logged in, how do you correctly calculate my bandwidth and charge appropriately while still protecting my auth tokens if there is no auth server? Who generates the auth tokens is not relevant to my question.
