Amazon Cognito is a robust authentication service provided by AWS that allows developers to add user sign-up, sign-in, and access control to their web and mobile applications. It is designed to handle the heavy lifting of authentication, authorization, and user management, making it easier for developers to focus on building their applications.
When working with Amazon Cognito, you might encounter the UserNotConfirmedException
error. This error typically occurs when a user attempts to sign in but their account has not been confirmed. The symptom is usually an error message indicating that the user is not confirmed.
This error often arises during the user sign-up process when the user has not completed the confirmation step, which is essential for activating their account.
The UserNotConfirmedException
is an error code that signifies that the user account exists but has not been confirmed. In Amazon Cognito, after a user signs up, they typically receive a confirmation code via email or SMS. This code must be entered to confirm and activate the account.
Account confirmation is a security measure to ensure that the email or phone number provided by the user is valid and accessible by them. It helps prevent unauthorized access and ensures that the user is genuine.
To resolve this issue, you need to guide the user through the account confirmation process. Here are the steps:
First, ensure that the user has received the confirmation code. If not, you can resend it using the AWS SDK or AWS CLI. Here is a sample command using AWS CLI:
aws cognito-idp resend-confirmation-code --client-id --username
Replace <your_client_id>
and <user_email_or_phone>
with your actual client ID and the user's email or phone number.
Once the user receives the confirmation code, they need to confirm their account. This can be done using the AWS SDK or AWS CLI. Here is a sample command:
aws cognito-idp confirm-sign-up --client-id --username --confirmation-code
Ensure the user enters the correct confirmation code they received.
For more detailed information, you can refer to the AWS Cognito Developer Guide and the AWS CLI Command Reference for Cognito.
By following these steps, you should be able to resolve the UserNotConfirmedException
and ensure that users can successfully confirm their accounts and sign in.
