For more information, see the following documentation: https://docs.aws.amazon.com/sdk-for-kotlin/latest/developer-guide/setup.html TIP: To set up the required user pool, run the AWS Cloud Development Kit (AWS CDK) script provided in this GitHub repo at resources/cdk/cognito_scenario_user_pool_with_mfa. This code example performs the following operations: 1. Invokes the signUp method to sign up a user. 2. Invokes the adminGetUser method to get the user's confirmation status. 3. Invokes the ResendConfirmationCode method if the user requested another code. 4. Invokes the confirmSignUp method. 5. Invokes the initiateAuth to sign in. This results in being prompted to set up TOTP (time-based one-time password). (The response is “ChallengeName”: “MFA_SETUP”). 6. Invokes the AssociateSoftwareToken method to generate a TOTP MFA private key. This can be used with Google Authenticator. 7. Invokes the VerifySoftwareToken method to verify the TOTP and register for MFA. 8. Invokes the AdminInitiateAuth to sign in again. This results in being prompted to submit a TOTP (Response: “ChallengeName”: “SOFTWARE_TOKEN_MFA”). 9. Invokes the AdminRespondToAuthChallenge to get back a token. */ suspend fun main(args: Array<String>) { val usage = """ Usage: <clientId> <poolId> Where: clientId - The app client Id value that you can get from the AWS CDK script. poolId - The pool Id that you can get from the AWS CDK script.
