adding email alias

[ErhardScampi]

Amplify CLI Version

12.1.1

Question

I have an amplify app grown up from version 5 up to now inclusive a painful migration to transformer v2.
Now the first user wants to change the email address. No problem there is a workflow to change the attribute email. But the user can't login with his new email address. He needs the old one which is still in the name. So I learned I need a login alias email. How can I configure it. When I fire amplify update auth and go thru all steps there is no alias question.
Is the perhaps a possibility to change the name also ?
In the name the old email is in Cognito (thru the console) in the email the new one.
How can I login with the new email address ?

Hey @ErhardScampi, thank you for reaching out. The Cognito sign-in attributes cannot be modified once the user pool has been created. Amplify CLI provides the capability of adding Alias attributes using the feature flag forceAliasAttributes in the amplify/cli.json, but would require us to recreate the Cognito user pool.

A workflow to change the attribute email currently exists, but the user can't login with his new email address.

Curious on what occurred here, could you provide us some on how the auth resource and workflow is currently configured?
Additionally, information on the behaviour the user observed on a login post updating the email address and if you observe the user being updated on the Cognito user pool?
