Cognito

Describe the feature you'd like to request

Stems from the GH issue : aws-amplify/amplify-js#987

Amplify Cognito pools are set up so that users can log in with their email. We also utilize attribute verification so that once a user signs up, they will need to verify their email address. Where we get stuck is when a user needs to update their email address. We call updateAttributes and pass their email, which will then send the user a verification email with the confirmation code. There are however states where the user is unauthenticated and needs to verify email with the confirmation code. If they are in an unauthenticated state, they need to authenticate. However, cognito doesn't allow users to log back in with neither their old or new email address. Instead, they need to sign up for an account again. This is a huge issue for us since it leaves users in this limbo state.

Cognito released a attribute in userpool UserAttributeUpdateSettings to have users old emails backwards compatible till they verify the new emails login.

Describe the solution you'd like

Introduce a new attribute UserAttributeUpdateSettings in amplify generated Cognito userPools

Since amplify uses an old version of cdk , Amplify dependencies needs to be update for cdk to latest version which supports this attribute.

Describe alternatives you've considered

One alternative can be to add this attribute to userPool after generating CFN templates using template modifiers during push but this may not help in long term code quality.
