I am confused on relationship between registration id and tokens. In the tutorial for GCM from Google, we register for a registration id in the beginning. However, we also get a token. Now, in the diagrams, we send the registration id to the targeted server. However, do we also send the token? I know that the token is derived from the registration id. Is the token used as an authentication mechanism between GCM and the app and the server never knows about the token?
