Working with the "Login with Facebook" Button

The “Login with Facebook” button

Until now, we have talked quite a bit about the “Login with Facebook” button. Ultimately, somewhere on the front-end of your application, you will deploy this button. This button which takes your users to Facebook, asks for them to authorize your app to access their data, and then returns your user back to your web application.

We are going to talk in more detail about this authorization flow in the next lesson. For now, we just need to finish out the rest of our app setup so that you can get your hands on an access token.
