I am developing my first WCF web service which is supposed to be interacting with two additional systems. I wish to implement authentication, but I am not certain of which options I have nor which one I should choose.
It is intended only for machine-to-machine communication, so forms should be out of the question. What’s the recommended method of authentication given the circumstances?
I think certificate based authentication is the way to go here.
Since machine to machine communication does not involve user input I suppose.
