Facebook - Unity3d desktop application

Question

Currently unity facebook sdk is not supported in desktop version. How can I implement facebook login in unity desktop application?

Answer 1

Your assumption is correct, you cannot directly login to Facebook from a desktop app.

However, you can use Application.OpenURL() to fire up a browser window and grab the access token once the user logins to Facebook and gives your app the required privileges.
