Available since 1.28.0.


This section will cover how to add a Login with Steam button to FusionAuth. Below is an example login page with the Steam Identity Provider enabled.

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

Steam Login

Create a Steam Account

Follow instructions for obtaining a Client id and Client secret from the official Steam documentation.

Steam - Getting Started

Create a Steam Identity Provider

To enable this identity provider for an application, find your application name in the Applications configuration section at the bottom of this panel. You will always see the FusionAuth application, this application represents the FusionAuth administrative user interface. If you wish to be able to log into FusionAuth with this provider, you may enable this application.

In the following screenshot you will see that we have enabled this login provider for the Pied Piper application and enabled Create registration. Enabling create registration means that a user does not need to be manually registered for the application prior to using this login provider.

For example, when a new user attempts to log into Pied Piper using Steam, if their user does not exist in FusionAuth it will be created dynamically, and if the Create registration toggle has been enabled, the user will also be registered for Pied Piper and assigned any default roles assigned by the application.

If you do not wish to automatically provision a user for this application when logging in with Steam, leave Create registration off. You will need to manually register a user for this application before they may Sign in with Steam.

That's it, now the Sign in with Steam button will show up on the login page for the Pied Piper application.

Form Fields

Client Idrequired
The unique client identifier obtained from Steam. See Steam - Getting Started.
API modeoptionalDefaults to Publicavailable since 1.44.0
Determines which Steam API to utilize. The possible values are:
  • Partner - The Steam partner API is used. https://partner.steam-api.com
  • Public - The public Steam API is used. https://api.steampowered.com
The only functional difference between these two APIs is that the public API is rate limited, and the partner API is not. If you are a Steam partner, you will want to set this value to Partner. Prior to version 1.44.0, the public API was always used.
Web API keyrequired
The client secret obtained from Steam used to authenticate the request. See Steam - Getting Started.
Button textoptional
The text to be displayed in the button on the login form. This value is defaulted to Login with Steam but it may be modified to your preference.
Linking strategyoptionalDefaults to Create a pending link
The linking strategy for the Steam provider. See Linking Strategies for more.
Reconcile lambdaoptional
A lambda maps custom claims returned from Steam to the FusionAuth User or Registration. To create or configure a lambda, navigate to Customizations -> Lambdas. See the lambda documentation for more.
Debug enabledoptionalDefaults to false
Enable debug to create event log entries during the user login process. This will assist you in debugging integration issues.

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.

Completing the login is documented further in the API.

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.
