#### [ CLI ]

**AWS CLI**  
**Respuesta a un desafío de autenticación**  
Hay muchas maneras de responder a los diferentes desafíos de autenticación, en función del flujo de autenticación, la configuración del grupo de usuarios y los ajustes de los usuarios. En el siguiente ejemplo de `admin-respond-to-auth-challenge`, se proporciona un código MFA con TOTP para diego@example.com y se completa el inicio de sesión. Este grupo de usuarios tiene activada la función de recordar dispositivos, por lo que el resultado de la autenticación también devuelve una nueva clave de dispositivo.  

```
aws cognito-idp admin-respond-to-auth-challenge \
    --user-pool-id us-west-2_EXAMPLE \
    --client-id 1example23456789 \
    --challenge-name SOFTWARE_TOKEN_MFA \
    --challenge-responses USERNAME=diego@example.com,SOFTWARE_TOKEN_MFA_CODE=000000 \
    --session AYABeExample...
```

**Creación de un grupo de usuarios con dos atributos obligatorios**  
En este ejemplo se crea un grupo de usuarios MyUserPool. El grupo está configurado para aceptar un correo electrónico como atributo de nombre de usuario. También establece la dirección de origen del correo electrónico en una dirección validada mediante Amazon Simple Email Service.  
Comando:  

```
aws cognito-idp create-user-pool --pool-name MyUserPool --username-attributes "email" --email-configuration=SourceArn="arn:aws:ses:us-east-1:111111111111:identity/jane@example.com",ReplyToEmailAddress="jane@example.com"

# Escenarios en los que Amazon Cognito Identity Provider utiliza AWS SDKs
<a name="service_code_examples_cognito-identity-provider_scenarios"></a>

Los siguientes ejemplos de código muestran cómo implementar escenarios comunes en Amazon Cognito Identity Provider con. AWS SDKs Estos escenarios muestran cómo realizar tareas específicas llamando a varias funciones dentro del proveedor de identidades de Amazon Cognito o en combinación con otros Servicios de AWS. En cada escenario se incluye un enlace al código fuente completo, con instrucciones de configuración y ejecución del código. 

Los escenarios requieren un nivel intermedio de experiencia para entender las acciones de servicio en su contexto.

# Migre automáticamente los usuarios conocidos de Amazon Cognito con una función Lambda mediante un SDK AWS
<a name="cognito-identity-provider_example_cross_CognitoAutoMigrateUser_section"></a>

En el siguiente ejemplo de código, se muestra cómo migrar de manera automática los usuarios conocidos de Amazon Cognito con una función de Lambda.
+ Configure un grupo de usuarios para que llame a una función de Lambda para el desencadenador `MigrateUser`.
+ Inicie sesión en Amazon Cognito con un nombre de usuario y un correo electrónico que no estén en el grupo de usuarios.
+ La función de Lambda escanea una tabla de DynamoDB y migra de manera automática los usuarios conocidos al grupo de usuarios.
+ Realice el flujo en caso de olvido de contraseña para restablecer la contraseña respecto del usuario migrado.
+ Inicie sesión como un nuevo usuario y, a continuación, elimine los recursos.

/**
 * Before running this Java V2 code example, set up your development
 * environment, including your credentials.
 *
 * For more information, see the following documentation:
 *
 * https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/get-started.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 AdminInitiateAuth 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.

#### [ Kotlin ]

**SDK para Kotlin**  
 Hay más información GitHub. Busque el ejemplo completo y aprenda a configurar y ejecutar en el [Repositorio de ejemplos de código de AWS](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/kotlin/services/cognito#code-examples).

/**
 Before running this Kotlin code example, set up your development environment, including your credentials.

 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.

// 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 example performs the following functions:
//
// 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.
