Amazon Cognito identity pools integrate with Facebook to provide federated authentication for your mobile application users. This section explains how to register and set up your application with Facebook as an IdP.
To add Facebook authentication, first follow the appropriate flow below to integrate the Facebook SDK into your application. Amazon Cognito identity pools use the Facebook access token to generate a unique user identifier that is associated with an Amazon Cognito identity.

The Facebook login process initializes a singleton session in its SDK. The Facebook session object contains an OAuth token that Amazon Cognito uses to generate AWS credentials for your authenticated end user. Amazon Cognito also uses the token to check against your user database for the existence of a user that matches this particular Facebook identity. If the user already exists, the API returns the existing identifier. Otherwise, the API returns a new identifier. The client SDK automatically caches identifiers on the local device.
To add Facebook authentication, first follow the Facebook guide and integrate the Facebook SDK into your application. Then add a Login with Facebook button to your user interface. The Facebook SDK uses a session object to track its state. Amazon Cognito uses the access token from this session object to authenticate the user and bind them to a unique Amazon Cognito identity pools (federated identities).
When you instantiate the AWSCognitoCredentialsProvider, pass the class that implements AWSIdentityProviderManager as the value of identityProviderManager in the constructor. For more information, go to the AWSCognitoCredentialsProvider reference page and choose initWithRegionType:identityPoolId:identityProviderManager.

FusionAuth will also store the Facebook long-lived token returned from the /oauth/access_token (after presenting the login token) in the identityProviderLink object. This object is accessible using the Link API.
The maximum number of links that a user can have for a particular identity provider. This configuration is specific to this IdP. So a user can have more links than this number, but for this particular IdP, the number of links will be limited and enforced.
If createRegistration has been enabled for this identity provider and the user does not yet have a registration for this application, a registration will be automatically created for the user. The user will be assigned any default roles configured for the application.
The pending identity provider link Id. This value is created when logging in with an identity provider configured with a linking strategy of Create a pending link. It will only be included in the response body when this strategy is configured and a link does not yet exist for the user. It is used in conjunction with the Link APIs to complete a pending link.
If you want to get access to the Facebook API key, you should register or sign up with your existing Facebook account on the developers portal and approve your identity. This will take just some simple following steps:
This concept of the portable identity has been talked about for years and the giant bubble of social networking sites has only increased the need for such a concept. Identity authentication with Twitter or Facebook connect is a logical next step and, unfortunately, professional networks like LinkedIn have missed the boat.
I think a great example for the potential of a portable online identity can be found in the online social networking platform Ning.com. Ning is basically a social network of social networks and allows one to sign up very easily.
The key to the concept that Ning has created is that as you connect or join with social networks on the platform, each social network can ask you a series of questions relevant to their network. This kind of additive approach to building your online identity allows each network to gather relevant information over time, instead of having you fill out a giant, generic profile (like Facebook or LinkedIn).
Here, the claims which are marked as mandatory are requested bythe service provider from the identity provider. If they are notavailable, the user will be redirected to a different page torequest those mandatory claim values from the user as they aremandatory.
You have successfully configured facebook as your federated authenticator. Now, when you try to log in to your application, it should redirect to the Facebook login page. On successful authentication with your Facebook credentials, you will be able to access your application.
This article will cover how to set up account linking in the Curity Identity Server, and requires a version of 7.5 or later. An HTML Authenticator will be used as a local authenticator, to capture the locally held identity that is going to be linked with a Facebook account. The flow will even be able to capture registration of the local account as needed but in a realistic scenario the local account already exists.
Click Add to add the first action in our sequence. Choose New Action, give it a name (html-authenticator) and choose the type Multi Factor Condition, click Next. Ensure that the option for Disable Second Factor Subject Check is selected. This action will cause the HTML Authenticator to be triggered. If the user already has a local account an authentication here will capture that identity and later use that for the linking. If the user doesn't have a local account, the HTML Authenticator can be used to create the account.
The most commonly used approaches for authenticating a user and obtaining an ID token are called the "server" flow and the "implicit" flow. The server flow allows the back-end server of an application to verify the identity of the person using a browser or mobile device. The implicit flow is used when a client-side application (typically a JavaScript app running in the browser) needs to access APIs directly instead of via its back-end server.
For best results, use Amazon Cognito as your identity broker for almost all web identity federation scenarios. Amazon Cognito is easy to use and provides additional capabilities like anonymous (unauthenticated) access, and synchronizing user data across devices and providers. However, if you have already created an app that uses web identity federation by manually calling the AssumeRoleWithWebIdentity API, you can continue to use it and your apps will still work fine.
To help understand how web identity federation works, you can use the Web Identity Federation Playground. This interactive website lets you walk through the process of authenticating via Login with Amazon, Facebook, or Google, getting temporary security credentials, and then using those credentials to make a request to Amazon.
Sign up as a developer with the external identity provider (IdP) and configure your app with the IdP, who gives you a unique ID for your app. (Different IdPs use different terminology for this process. This outline uses the term configure for the process of identifying your app with the IdP.) Each IdP gives you an app ID that's unique to that IdP, so if you configure the same app with multiple IdPs, your app will have multiple app IDs. You can configure multiple apps with each provider.
If you use an OIDC identity provider from Google, Facebook, or Amazon Cognito, do not create a separate IAM identity provider in the Amazon Web Services Management Console. Amazon has these OIDC identity providers built-in and available for your use. Skip the following step and move directly to creating new roles using your identity provider. 2ff7e9595c
