After a user successfully authenticates with Facebook for Web Identity Federation, they receive an ID token from Facebook. This ID token is a JSON Web Token (JWT) that contains information about the user’s identity, including their unique identifier and potentially other profile information. This token is then used to grant the user temporary AWS credentials via AWS Security Token Service (STS).

The ID token serves as proof of the user’s authenticated status and allows AWS to validate the user's identity without needing to handle their Facebook credentials directly. This process ensures a secure and seamless way for users to access AWS resources using their existing Facebook account.

The other options do not accurately describe the immediate outcomes of the authentication process with Facebook. For instance, long-term credentials are not provided directly after authentication; instead, it's temporary AWS credentials that are issued based on the received ID token. Users are also not redirected to the AWS Console nor required to log in again with AWS credentials after authenticating with Facebook. The integration is designed to streamline access through the use of the Facebook identity.
