Follow the steps below to configure the login in the Publisher Dashboard:
Go to Settings -> Authentication.
Toggle on Facebook App, and enter your Facebook ID in the Facebook App ID field.
The button for logging in with Facebook will appear in the web store login page.
Once a player selects this method, Facebook generates a token. Apppcharge sends this token along with other login information to your Authenticate Player API for verification.
Once verified, the player is logged into the web store.
