Twitch Identity Provider
This feature is only available in paid editions of FusionAuth. Please visit our pricing page to learn more about paid editions.
Available since 1.28.0.
This section will cover how to add a Login with Twitch button to FusionAuth. Below is an example login page with the Twitch Identity Provider enabled.
Once you have completed this configuration you will be able to enable the Twitch login button for one or more FusionAuth Applications. Below is an example login page with the Twitch Identity Provider enabled.
Ensure you have a Twitch account, and then navigate to the Twitch Developer dashboard. Please note that you will need to have verified your account and enabled two-factor authentication.
Create a Twitch Account
If you do not yet have a Twitch app you will need to create an app in this step. If you already have a Twitch app that you plan to use for FusionAuth, please review this section anyway to ensure your configuration is correct to support the Twitch Identity Provider.
In the following screenshot you will find an example of creating an application in Twitch. Review the following sections to ensure your configuration is correct. Fill out any required fields found on this form and click the
Create button to create a new Twitter app.
Add the Callback URL
In this example I have registered
https://login.piedpiper.com/oauth-callback as the callback URL. Please note that Twitch requires this URL to use the
Choose a Category
You can select the category of the application for which you are enabling the ability to login with Twitch.
Keys and token
Once you click
Create, you will be redirected back to the dashboard for applications. From there, you will have to click
Manage to view the client id and the client secret. Create a secret by clicking on the "New Secret" button. These two values will be used to configure the FusionAuth Identity Provider.
There is no further configuration to perform on this panel, you will only need to record or copy these values for the next step.
Once you have completed this configuration you will be able to enable the Twitch login button for one or more FusionAuth Applications.
Create a Twitch 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 Twitch, 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 Twitch, leave
Create registration off. You will need to manually register a user for this application before they may
Sign in with Twitch.
That’s it, now the
Sign in with Twitch button will show up 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.
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 .
