Facebook Identity Provider | Login with Facebook

Create a New App Id

Click on the Create App button to create a new Facebook application. The application Display Name will be shown to users when they log into FusionAuth using Facebook. Complete this form and click the Create App button.

Configure Facebook Login

In order to enable Facebook login for this newly created Application, add the Facebook Login product to this application. The Add a Product is likely the first page you’ll see after creating the Application, but if not find the Products + or Add Product section and find the Facebook Login tile and click Set Up.

You’ll now have the Facebook Login product listed under the Products section of your application. Click on the Settings sub-menu of the Facebook Login section in the left navigation. Review this page to ensure it meets your security requirements, however the default Client OAuth Settings should be sufficient.

If you are using the redirect login method, you will want to add the absolute URL to the callback endpoint (for example, https://login.piedpiper.com/oauth2/callback) to the Valid OAuth Redirect URIs field.

If you are using the popup login method, provide an App Domain, User Data Deletion field, and Privacy Policy URL. When selecting a domain, add the top level domain of your application in the App Domains field (for example, in our app we added piedpiper.com because our application login will originate from https://login.piedpiper.com).

Collect App ID and App Secret

To complete the configuration you will need to collect the App ID and the App Secret to use in the FusionAuth configuration. To find these values, navigate to Settings → Basic in the left navigation.

You can either record these values now, or keep this page open so you can copy and paste these values during the next step in FusionAuth.

Note the mode of your application begins as development. To make this application public or live you will need to toggle the App Mode button. If toggled to live you will be prompted by Facebook to complete a few other settings. However, you may still use this application to login while in this non-public state.
