Hi there- Currently, you would need to use Cognito Federated Identities if you desire to assume an IAM role for direct AWS resource access. However, this will only created a unique id for the users and not store their profile information from Facebook/Google. To do this currently, you'd need to have your app save this to a DynamoDB table or some sort of other persistence store. There is currently an option to create user account automatically and sync their profile information from SAML identity providers for Cognito User Pools, but not for FB/Google, etc. This may be an option in the future based on the documentation saying other IdPs will be supported later, but for now you'll need to implement this attribute syncing and capturing yourself.
