@interface AWSCognitoIdentityProviderSmsConfigurationType

Swift

class AWSCognitoIdentityProviderSmsConfigurationType

The SMS configuration type is the settings that your Amazon Cognito user pool must use to send an SMS message from your Amazon Web Services account through Amazon Simple Notification Service. To send SMS messages with Amazon SNS in the Amazon Web Services Region that you want, the Amazon Cognito user pool uses an Identity and Access Management (IAM) role in your Amazon Web Services account.

Required parameters: [SnsCallerArn]

  • The external ID provides additional security for your IAM role. You can use an ExternalId with the IAM role that you use with Amazon SNS to send SMS messages for your user pool. If you provide an ExternalId, your Amazon Cognito user pool includes it in the request to assume your IAM role. You can configure the role trust policy to require that Amazon Cognito, and any principal, provide the ExternalID. If you use the Amazon Cognito Management Console to create a role for SMS multi-factor authentication (MFA), Amazon Cognito creates a role with the required permissions and a trust policy that demonstrates use of the ExternalId.

    For more information about the ExternalId of a role, see How to use an external ID when granting access to your Amazon Web Services resources to a third party
