Using Cognito User Pools, without Cognito Federated Identities(identity pools)

Question

I would like to use only Cognito User Pool, and therefore I want to use identity federation with Cognito User Pools, without Cognito Federated Identities (identity pools).

Answer 1

Looks like they only allow User Pool Federation with their own UI/SDK. What I ended up doing for react-native was

• get facebook token

• sign up the user into the user pool with a custom attribute to track facebook Id and generic password

• use the temporary credentials (need to setup IAM for cognito user pool - adminMovetoGroup to move the user into the auto created user pool federated group.

• create lambda function to auto-confirm the end user.

This way the user can log in and get credentials using federated identities, but then they also have an account in the event they stop using facebook. They would also need to reset their password.
