Cognito unable to signup users that have unconfirmed status already

A Cognito User Pool is configured for the users to use their "email address" to sign up and sign in.



If a user signs up with the email of someone else then that email will get stuck in UNCONFIRMED state and the owner will not be able to use it appropriately.



Having said that let me provide an example with the following scenario:




  1. User signs in with an email address the user doesn't own, let's say it is someone@mail.com. In this step (registration form) some more data is sent like organization name, and user full name.

  2. Verification code is sent to the email

  3. Now the user that owns someone@email.com wants to create an account (maybe some days in the future), so he goes and fills the registration form but an error is thrown by cognito {"__type":"UsernameExistsException","message":"An account with the given email already exists."}


Thinks to consider:
* If the email already exists but is in unconfirmed state then provide the user the option to resend the link. This option is not optimal because additional data might be already in the user profile as the 1st step exemplifies.
* A custom lambda can be done to delete the unconfirmed user before signup or as a maintenance process every day, but I am not sure if this is the best approach.




There is also this configuration under Policies in cognito consol: "How quickly should user accounts created by administrators expire if not used?", but as he name implies this setting will only apply to users if they are invited by admins.




Is there a proper solution for this predicament?

  • I think the way it currently works in correct. The options you have are:1) Admin has to delete the user manually 2) User signs in with the password received, then corrects his information
