My main goal is to connect devices but only with an access token and not by manually adding devices to the cloud IoT platform
Is there a platform to do that automatically? How to do it/Which platform is good for that purpose?
why I asked this question?: I have used Node-RED, thinger.io, and thingspeak. However, in most of them, we should add device manually and make a device auth token is it possible to add a device automatically and subscribe to a topic(topic name is the same one) and get data without manually adding devices Basically, I need an automatic device registry either based on tokens or using username and password login.
