Facebook authentication

In order to set up Discord authentication, you need to register an application on Discord. This can be done from the Discord website.

Registering an application

  1. Go to https://developers.facebook.com/ and log in with your Facebook account.

  2. Under the “My Apps” menu, click “Create New App.”

  3. Give your application a name and provide your contact email address.


    You should choose a name that reflects the community you have set up FreeField for. A good idea is to use the name of your community, or a location-specific name such as “New York FreeField.” You may optionally upload an icon for your application, which will be displayed when users attempt to authenticate.

  4. Click on Create App ID. If you are prompted to provide human verification, do so and click Confirm.

  1. When prompted to select a Scanario, select “Integrate Facebook Login” and click Confirm.
  1. Take note of the “App ID” and “App Secret” assigned to your application:
  1. On the same page, look for “Facebook Login” in the sidebar menu. Click on it, then click on the “Settings” sub-option to navigate to the authentication options.
  2. In the “Valid OAuth Redirect URIs” field, paste the redirect URL for FreeField’s implementation of OAuth2 with Facebook. This URL is auth/oa2/facebook.php, relative to your installation path. E.g. if you have installed FreeField to https://example.com/freefield/, the redirect URL would be https://example.com/freefield/auth/oa2/facebook.php.
    • If your FreeField installation does not support HTTPS, make sure to disable “Enforce HTTPS” on this page as well.
  1. Click “Save Changes” to save the settings.

Enabling Facebook authentication in FreeField

After you have registered an application on Facebook, you can configure FreeField to use Facebook for authentication.

  1. In the FreeField administration pages, navigate to the “Authentication” menu.
  2. In the Facebook section, check the box next to “Enable Facebook authentication” and paste the app ID and secret you got from Facebook in the relevant fields.
  1. Save the setting using Save settings at the bottom of the page.
