@atindraojha, I'm forwarding this issue to the Amplify JS team for better support.

Hello, @atindraojha 👋. It sounds like you're needing to use the AdminLinkProviderForUser API within Cognito to recognize a user's unique ID in your federated directory as a user in the user pool. You can reference these docs for more information on that admin API as well as this guide.

Let me know if that helps clear things up!

I am facing the same issue. I am using Amplify Authenticator for sign-up with both an external provider (Google) and email. How can I merge both sign-ups into a single user?

I am signing up using Google with the email like vishal@yopmail.com, and also signing up with the same email via the email sign-up method. However, Cognito creates two separate users. I want to combine them into one user.
