In this tutorial, you will learn how to enable login method in the AccelByte Gaming Services (AGS) Admin Portal for single platform auth.

Set up Steam login method​

  1. Log in to the Admin Portal and go to your game namespace dashboard.

  2. On the sidebar menu, select Game Setup > 3rd Party Configuration > Auth & Account Linking. Click the Add New button at the top right of the page.

  3. Choose Steam SDK and fill in the required fields:

    • App ID: Your game's App ID from the Steam partner dashboard (see Applications from Steam).
    • Steam Web API Key: The Web API Key acquired from Steam (see Steam Web API Documentation).
    • Redirect URI: Enter http://127.0.0.1.

  4. After applying the changes, you will see Steam SDK in the list of login methods. Ensure that its Status is set to Active.

Set up Epic Online Services (EOS) login method​

  2. On the sidebar menu, select Game Setup > 3rd Party Configuration > Auth & Account Linking. Click the Add New button at the top right of the page.

    • Client ID: Your EOS product's client ID.
    • Client Secret: Your EOS product's client secret.
    • Redirect URI: Enter http://127.0.0.1.

  4. After applying the changes, you will see Epic Games in the list of login methods. Ensure that its Status is set to Active.

Configure single platform auth OSS​

To implement single platform authentication, you need to configure the platform Online Subsystem (OSS) in the project and set up the NativePlatformService. In the Byte Wars project, we've separated the DefaultEngine.ini file and the .Target.cs for each platform, making it easy to build and run the game based on the selected platform.

Set up Steam OSS​

  1. Open the AccelByteWars.uproject file and ensure that the OnlineSubsystemSteam plugin is enabled.

    {
        ...
        "Plugins": [
            ...
            {
                "Name": "OnlineSubsystemSteam",
                "Enabled": true
            }
        ]
    }

  2. Head to the Config/Custom/Steam/DefaultEngine.ini file and look for the [OnlineSubsystemSteam] section. Ensure that the bEnabled flag is set to true and the SteamDevAppId is set to your Steam App ID.

    [OnlineSubsystemSteam]
    bEnabled=true
    SteamDevAppId="<Your Steam App ID>"
    bUseSteamNetworking=false

  3. In the same file, ensure the value of NativePlatformService is set to Steam under the [OnlineSubsystem] section.

    [OnlineSubsystem]
    NativePlatformService=Steam

Set up Epic Online Services (EOS) OSS​

  1. Open the AccelByteWars.uproject file and ensure that the OnlineSubsystemEOS plugin is enabled.

    {
        ...
        "Plugins": [
            ...
            {
                "Name": "OnlineSubsystemEOS",
                "Enabled": true
            }
        ]
    }

  2. Head to the Config/Custom/EOS/DefaultEngine.ini file and look for the [OnlineSubsystemEOS] and the [/Script/OnlineSubsystemEOS.EOSSettings] section. Make sure to set the bEnabled to true and fill the EOS credentials with your EOS product details. For more information about EOS settings, refer to the EOS official documentation.

    [OnlineSubsystemEOS]
    bEnabled=true

    [/Script/OnlineSubsystemEOS.EOSSettings]
    DefaultArtifactName=<your-artifact-name>
    +Artifacts=(ArtifactName="<your-artifact-name>",ProductId="<your-product-ID>",SandboxId="<your-sandbox-ID>",DeploymentId="<your-deployment-ID>",ClientId="<your-client-ID>",ClientSecret="<your-client-secret>/NWQgLmEb060qWRohr05nVaE",EncryptionKey="1111111111111111111111111111111111111111111111111111111111111111")
    bUseEAS=True

  3. In the same file, ensure the value of NativePlatformService is set to EOS under the [OnlineSubsystem] section.

    [OnlineSubsystem]
    NativePlatformService=EOS
