Facebook Identity Provider | Login with Facebook
Adding a Login with Facebook button to FusionAuth is straightforward, and this guide will walk you through the steps necessary to collect the credentials from Facebook in order to enable this Social login.
Once you have completed this configuration you will be able to enable the Facebook login button for one or more FusionAuth Applications. Below is an example login page with the Facebook Identity Provider enabled.
Create a Facebook Account
If you do not yet have a Facebook account, go ahead and do that first. If you need help with this step, ask your kids.
Add a Facebook Application
In order to enable the Login with Facebook option in FusionAuth we’ll need to add a Facebook application. Follow the provided link or navigate to your Facebook developer account to continue.
Create a New App Id
Click on the
Create App button to create a new Facebook application. The application
Display Name will be shown to users when they log into FusionAuth using Facebook. Complete this form and click the
Create App button.
Configure Facebook Login
In order to enable Facebook login for this newly created Application, add the
Facebook Login product to this application. The
Add a Product is likely the first page you’ll see after creating the Application, but if not find the
Products + or
Add Product section and find the
Facebook Login tile and click
You’ll now have the
Facebook Login product listed under the
Products section of your application. Click on the
Settings sub-menu of the
Facebook Login section in the left navigation. Review this page to ensure it meets your security requirements, however the default Client OAuth Settings should be sufficient.
If you are using the redirect login method, you will want to add the absolute URL to the callback endpoint (for example,
https://login.piedpiper.com/oauth2/callback) to the
Valid OAuth Redirect URIs field.
If you are using the popup login method, provide an
User Data Deletion field, and
App Domains field (for example, in our app we added
piedpiper.com because our application login will originate from
Collect App ID and App Secret
To complete the configuration you will need to collect the
App ID and the
App Secret to use in the FusionAuth configuration. To find these values, navigate to in the left navigation.
You can either record these values now, or keep this page open so you can copy and paste these values during the next step in FusionAuth.
Note the mode of your application begins as
development. To make this application public or
live you will need to toggle the
App Mode button. If toggled to
live you will be prompted by Facebook to complete a few other settings. However, you may still use this application to login while in this non-public state.
Create a Facebook Identity Provider
The last step will be to create a Facebook Identity Provider in FusionAuth. To create an Identity Provider navigate to
Add provider and select
This will take you to the
Add Facebook panel, and you’ll fill out the
App Id and
App Secret required fields using the values from the Facebook console. The button text is also required but it will be defaulted to
Login with Facebook, you may optionally modify this default value.
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 Facebook, 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 Facebook, leave
Create registration off. You will need to manually register a user for this application before they may
Sign in with Facebook.
That’s it, now the
Sign in with Facebook button will show up on the login page for the Pied Piper application.

Use redirect for login- if selected, the user is redirected to a Facebook login page. Once authenticated, the user is redirected back to FusionAuth.

Use popup for login- if selected, a popup is displayed to the user to login with Facebook. Once authenticated, the window is closed. If using
Use Popup for loginyou will need to fill in an

Enable debug to create an event log to assist you in debugging integration errors.
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 .
