This section explains how to add a Login with Epic Games button to FusionAuth. Below is an example login page with the Epic Games Identity Provider enabled.

Once you have completed this configuration you will be able to enable the Epic Games login button for one or more FusionAuth Applications. Below is an example login page with the Epic Games Identity Provider enabled.

Here's a diagram of the login flow between:

  • the user
  • your application
  • FusionAuth and
  • a remote identity provider

Although this looks complex, the user only sees a few screens, such as the FusionAuth login screen, the provider login screen, and your application.

Create an Epic Games Account#

Follow instructions for obtaining a Client id and Client secret from the Epic Games documentation.

Create an Epic Games Identity Provider#

To enable Epic Games for an Application:

  1. Navigate to Settings -> Identity Providers .

  2. Click the Add provider dropdown and select Epic Games . This will take you to the Add Epic Games screen.

  3. Fill out the required fields; your identity provider can provide most of these values. For more information about the fields required for each identity provider, see the documentation for your provider.

  4. In the Applications configuration section at the bottom of this panel, find your application name.

  5. To dynamically create FusionAuth user accounts (with default roles) for all users who successfully authenticate using this provider, select Create registration . If you disable this option, only an administrator with registration permissions can create new users for this application with access via Sign in with Epic Games.

  6. You should now see the Sign in with Epic Games button on the login page for the Pied Piper application.

Building Your Own Integration#

If you are building your own login experience, you'll want to start the identity provider flow yourself and then complete the login.

You might do this if you are using the Login API rather than using the hosted FusionAuth login pages. Here's a diagram illustrating this login flow:

If you require a refresh token after completing the login, ensure Enable JWT Refresh is true in the application configuration. This is found in the administrative user interface by navigating to Applications -> Your Application -> Security -> Login API settings .
