Hi there!

thanks to the DNN Documentation center I have successfully managed to implement JWT Login/Auth for my Smartphone App which is accessing different API-Endpoints on my DNN8 Module  / API Project. (http://www.dnnsoftware.com/docs/administrators/jwt/index.html)

This works great for Login from the App with Username/Password which is verified against the DNN-Users in the Database of the Portal and issues a Token that is then used to access my API Functions.

Now I want to allow the app-users to login/authenticate via their facebook login.

I read a lot of blogposts and articles that I found via google, but was not able to figure out how to transfer this to my situation.

and many more ... but it seems I do not find the right entry point for getting ahead with this demand.

I do not want to reinvent the wheel and i wonder if there a way to use what DNN already does for the facebook-authentication on the Portal Level to make it work from external Apps too.

Can anyone point me in the right direction how this can be implemented in my modules (JWT-) authentication or API mechanism

Any help is highly appreciated

Thanks in advance and kind regards
