Detect if user is not confirmed prior authentication

** Which Category is your question related to? ** Auth

** What AWS Services are you utilizing? ** Cognito

** Provide additional details e.g. code snippets ** In our configuration Cognito user has to verify the email address or the phone number they used to register the account. If the user does not verify the account and tries to login, Amplify throws a UserNotFoundException. Is there a way to distinguish wether the user is not registered from when they are registered but not confirmed?

Bump on this issue. It appears that if a user creates an account, but then leaves before being confirmed. And then later tries to:

1. Sign up–it says the account already exists
2. Sign in --it says the user is not confirmed.

So we do indeed need a way to know if the user is registered but not confirmed. In that case, when they try to sign in, they could sign in but then have to verify before proceeding.

I believe this ticket should be re-opened per the original description, which is slightly different than the last comment above. Steps to repro:

1. Sign up
2. Do not confirm email
3. Try to sign in
4. Expected: Some kind of specific error like UserNotConfirmedException
5. Actual: UserNotFoundException

This leaves the client app no way to distinguish between a user trying to sign in who never created an account versus a user who signed up but never entered the code. Sure, the user can simply sign up again. But we’re having users call Support when they exit the app for whatever reason before completing registration. They expect to be prompted to enter the code when they go back in.
