AWS CLI Command Reference

[ aws . cognito-idp ]

create-user-pool

Description

Creates a new Amazon Cognito user pool and sets the password policy for the pool.

Note

This action might generate an SMS text message. Starting June 1, 2021, US telecom carriers require you to register an origination phone number before you can send SMS messages to U.S. phone numbers. If you use SMS text messages in Amazon Cognito, you must register a phone number with Amazon Pinpoint . Amazon Cognito will use the registered number automatically. Otherwise, Amazon Cognito users that must receive SMS messages might be unable to sign up, activate their accounts, or sign in.

If you have never used SMS text messages with Amazon Cognito or any other Amazon Web Service, Amazon Simple Notification Service might place your account in SMS sandbox. In * sandbox mode * , you will have limitations, such as sending messages only to verified phone numbers. After testing in the sandbox environment, you can move out of the SMS sandbox and into production. For more information, see SMS message settings for Amazon Cognito User Pools in the Amazon Cognito Developer Guide .

  "DeviceOnlyRememberedOnUserPrompt": true|false
}

--email-configuration (structure)

The email configuration.

SourceArn -> (string)

The ARN of a verified email address in Amazon SES. Amazon Cognito uses this email address in one of the following ways, depending on the value that you specify for the EmailSendingAccount parameter:

  • If you specify COGNITO_DEFAULT , Amazon Cognito uses this address as the custom FROM address when it emails your users using its built-in email account.

  • If you specify DEVELOPER , Amazon Cognito emails your users with this address by calling Amazon SES on your behalf.

ReplyToEmailAddress -> (string)

The destination to which the receiver of the email should reply.

EmailSendingAccount -> (string)

Specifies whether Amazon Cognito emails your users by using its built-in email functionality or your Amazon Simple Email Service email configuration. Specify one of the following values:

COGNITO_DEFAULT

When Amazon Cognito emails your users, it uses its built-in email functionality. When you use the default option, Amazon Cognito allows only a limited number of emails each day for your user pool. For typical production environments, the default email limit is less than the required delivery volume. To achieve a higher delivery volume, specify DEVELOPER to use your Amazon SES email configuration.

To look up the email delivery limit for the default option, see Limits in in the Developer Guide .

The default FROM address is no-reply@verificationemail.com . To customize the FROM address, provide the Amazon Resource Name (ARN) of an Amazon SES verified email address for the SourceArn parameter.

If EmailSendingAccount is COGNITO_DEFAULT, you can’t use the following parameters:

  • EmailVerificationMessage

  • EmailVerificationSubject

  • InviteMessageTemplate.EmailMessage

  • InviteMessageTemplate.EmailSubject

  • VerificationMessageTemplate.EmailMessage

  • VerificationMessageTemplate.EmailMessageByLink

  • VerificationMessageTemplate.EmailSubject,

  • VerificationMessageTemplate.EmailSubjectByLink

Note

DEVELOPER EmailSendingAccount is required.

DEVELOPER

When Amazon Cognito emails your users, it uses your Amazon SES configuration. Amazon Cognito calls Amazon SES on your behalf to send email from your verified email address. When you use this option, the email delivery limits are the same limits that apply to your Amazon SES verified email address in your Amazon Web Services account.

If you use this option, you must provide the ARN of an Amazon SES verified email address for the SourceArn parameter.

Before Amazon Cognito can email your users, it requires additional permissions to call Amazon SES on your behalf. When you update your user pool with this option, Amazon Cognito creates a service-linked role , which is a type of role, in your Amazon Web Services account. This role contains the permissions that allow to access Amazon SES and send email messages with your address. For more information about the service-linked role that Amazon Cognito creates, see Using Service-Linked Roles for Amazon Cognito in the Amazon Cognito Developer Guide .

From -> (string)

Either the sender’s email address or the sender’s name with their email address. For example, testuser@example.com or Test User <testuser@example.com> . This address appears before the body of the email.

ConfigurationSet -> (string)

The set of configuration rules that can be applied to emails sent using Amazon Simple Email Service. A configuration set is applied to an email by including a reference to the configuration set in the headers of the email. Once applied, all of the rules in that configuration set are applied to the email. Configuration sets can be used to apply the following types of rules to emails:

  • Event publishing – Amazon Simple Email Service can track the number of send, delivery, open, click, bounce, and complaint events for each email sent. Use event publishing to send information about these events to other Amazon Web Services services such as and Amazon CloudWatch.

  • IP pool management – When leasing dedicated IP addresses with Amazon Simple Email Service, you can create groups of IP addresses, called dedicated IP pools. You can then associate the dedicated IP pools with configuration sets.

Shorthand Syntax:

SourceArn=string,ReplyToEmailAddress=string,EmailSendingAccount=string,From=string,ConfigurationSet=string

JSON Syntax:

{
  "SourceArn": "string",
  "ReplyToEmailAddress": "string",
  "EmailSendingAccount": "COGNITO_DEFAULT"|"DEVELOPER",
  "From": "string",
  "ConfigurationSet": "string"
}

--sms-configuration (structure)

The SMS configuration.

SnsCallerArn -> (string)

The Amazon Resource Name (ARN) of the Amazon SNS caller. This is the ARN of the IAM role in your Amazon Web Services account that Amazon Cognito will use to send SMS messages. SMS messages are subject to a spending limit .

ExternalId -> (string)

The external ID is a value that you should use to add security to your IAM role that is used to call Amazon SNS to send SMS messages for your user pool. If you provide an ExternalId , the Amazon Cognito User Pool will include it when attempting to assume your IAM role so that you can set your roles trust policy to require the ExternalID . If you use the Amazon Cognito Management Console to create a role for SMS multi-factor authentication (MFA), Amazon Cognito will create 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

Shorthand Syntax:

SnsCallerArn=string,ExternalId=string

JSON Syntax:

{
  "SnsCallerArn": "string",

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--admin-create-user-config (structure)

The configuration for AdminCreateUser requests.

AllowAdminCreateUserOnly -> (boolean)

Set to True if only the administrator is allowed to create user profiles. Set to False if users can sign themselves up via an app.

UnusedAccountValidityDays -> (integer)

The user account expiration limit, in days, after which the account is no longer usable. To reset the account after that time limit, you must call AdminCreateUser again, specifying "RESEND" for the MessageAction parameter. The default value for this parameter is 7.

Note

If you set a value for TemporaryPasswordValidityDays in PasswordPolicy , that value will be used, and UnusedAccountValidityDays will be no longer be an available parameter for that user pool.

InviteMessageTemplate -> (structure)

The message template to be used for the welcome message to new users.

See also Customizing User Invitation Messages .

SMSMessage -> (string)

The message template for SMS messages.

--schema (list)

An array of schema attributes for the new user pool. These attributes can be standard or custom attributes.

(structure)

Contains information about the schema attribute.

Name -> (string)

A schema attribute of the name type.

AttributeDataType -> (string)

The attribute data type.

DeveloperOnlyAttribute -> (boolean)

Note

You should use WriteAttributes in the user pool client to control how attributes can be mutated for new use cases instead of using DeveloperOnlyAttribute .

Specifies whether the attribute type is developer only. This attribute can only be modified by an administrator. Users won’t be able to modify this attribute using their access token. For example, DeveloperOnlyAttribute can be modified using AdminUpdateUserAttributes but can’t be updated using UpdateUserAttributes.

Mutable -> (boolean)

Specifies whether the value of the attribute can be changed.

For any user pool attribute that is mapped to an identity provider attribute, you must set this parameter to true . Amazon Cognito updates mapped attributes when users sign in to your application through an identity provider. If an attribute is immutable, Amazon Cognito throws an error when it attempts to update the attribute. For more information, see Specifying Identity Provider Attribute Mappings for Your User Pool .

Required -> (boolean)

Specifies whether a user pool attribute is required. If the attribute is required and the user doesn’t provide a value, registration or sign-in will fail.

JSON Syntax:

[
  {
    "Name": "string",
    "AttributeDataType": "String"|"Number"|"DateTime"|"Boolean",
    "DeveloperOnlyAttribute": true|false,
    "Mutable": true|false,

      "MinValue": "string",
      "MaxValue": "string"
    },
    "StringAttributeConstraints": {
      "MinLength": "string",
      "MaxLength": "string"
    }
  }
  ...
]

--user-pool-add-ons (structure)

Enables advanced security risk detection. Set the key AdvancedSecurityMode to the value “AUDIT”.

AdvancedSecurityMode -> (string)

The advanced security mode.

Shorthand Syntax:

AdvancedSecurityMode=string

JSON Syntax:

{
  "AdvancedSecurityMode": "OFF"|"AUDIT"|"ENFORCED"
}

--username-configuration (structure)

Case sensitivity on the username input for the selected sign-in option. For example, when case sensitivity is set to False , users can sign in using either “username” or “Username”. This configuration is immutable once it has been set. For more information, see UsernameConfigurationType .

CaseSensitive -> (boolean)

Specifies whether username case sensitivity will be applied for all users in the user pool through Amazon Cognito APIs.

Valid values include:

  • **True ** : Enables case sensitivity for all username input. When this option is set to True , users must sign in using the exact capitalization of their given username, such as “UserName”. This is the default value.

  • **False ** : Enables case insensitivity for all username input. For example, when this option is set to False , users can sign in using either “username” or “Username”. This option also enables both preferred_username and email alias to be case insensitive, in addition to the username attribute.

Shorthand Syntax:

CaseSensitive=boolean

JSON Syntax:

{
  "CaseSensitive": true|false
}

--account-recovery-setting (structure)

The available verified method a user can use to recover their password when they call ForgotPassword . You can use this setting to define a preferred method when a user has more than one method available. With this setting, SMS doesn’t qualify for a valid password recovery mechanism if the user also has SMS multi-factor authentication (MFA) activated. In the absence of this setting, Amazon Cognito uses the legacy behavior to determine the recovery method where SMS is preferred through email.

RecoveryMechanisms -> (list)

The list of RecoveryOptionTypes .

(structure)

A map containing a priority as a key, and recovery method name as a value.

Priority -> (integer)

A positive integer specifying priority of a method with 1 being the highest priority.

Name -> (string)

The recovery method for a user.

Shorthand Syntax:

RecoveryMechanisms=[{Priority=integer,Name=string},{Priority=integer,Name=string}]

JSON Syntax:

{
  "RecoveryMechanisms": [
    {
      "Priority": integer,
      "Name": "verified_email"|"verified_phone_number"|"admin_only"
    }
    ...
  ]
}

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

To create a user pool with two required attributes

This example creates a user pool MyUserPool. The pool is configured to accept email as a username attribute. It also sets the email source address to a validated address using Amazon Simple Email Service.

Command:

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"

SourceArn -> (string)

The ARN of a verified email address in Amazon SES. Amazon Cognito uses this email address in one of the following ways, depending on the value that you specify for the EmailSendingAccount parameter:

  • If you specify COGNITO_DEFAULT , Amazon Cognito uses this address as the custom FROM address when it emails your users using its built-in email account.

  • If you specify DEVELOPER , Amazon Cognito emails your users with this address by calling Amazon SES on your behalf.

ReplyToEmailAddress -> (string)

The destination to which the receiver of the email should reply.

EmailSendingAccount -> (string)

Specifies whether Amazon Cognito emails your users by using its built-in email functionality or your Amazon Simple Email Service email configuration. Specify one of the following values:

COGNITO_DEFAULT

When Amazon Cognito emails your users, it uses its built-in email functionality. When you use the default option, Amazon Cognito allows only a limited number of emails each day for your user pool. For typical production environments, the default email limit is less than the required delivery volume. To achieve a higher delivery volume, specify DEVELOPER to use your Amazon SES email configuration.

To look up the email delivery limit for the default option, see Limits in in the Developer Guide .

The default FROM address is no-reply@verificationemail.com . To customize the FROM address, provide the Amazon Resource Name (ARN) of an Amazon SES verified email address for the SourceArn parameter.

If EmailSendingAccount is COGNITO_DEFAULT, you can’t use the following parameters:

  • EmailVerificationMessage

  • EmailVerificationSubject

  • InviteMessageTemplate.EmailMessage

  • InviteMessageTemplate.EmailSubject

  • VerificationMessageTemplate.EmailMessage

  • VerificationMessageTemplate.EmailMessageByLink

  • VerificationMessageTemplate.EmailSubject,

  • VerificationMessageTemplate.EmailSubjectByLink

Note

DEVELOPER EmailSendingAccount is required.

DEVELOPER

When Amazon Cognito emails your users, it uses your Amazon SES configuration. Amazon Cognito calls Amazon SES on your behalf to send email from your verified email address. When you use this option, the email delivery limits are the same limits that apply to your Amazon SES verified email address in your Amazon Web Services account.

If you use this option, you must provide the ARN of an Amazon SES verified email address for the SourceArn parameter.

Before Amazon Cognito can email your users, it requires additional permissions to call Amazon SES on your behalf. When you update your user pool with this option, Amazon Cognito creates a service-linked role , which is a type of role, in your Amazon Web Services account. This role contains the permissions that allow to access Amazon SES and send email messages with your address. For more information about the service-linked role that Amazon Cognito creates, see Using Service-Linked Roles for Amazon Cognito in the Amazon Cognito Developer Guide .

From -> (string)

Either the sender’s email address or the sender’s name with their email address. For example, testuser@example.com or Test User <testuser@example.com> . This address appears before the body of the email.

ConfigurationSet -> (string)

The set of configuration rules that can be applied to emails sent using Amazon Simple Email Service. A configuration set is applied to an email by including a reference to the configuration set in the headers of the email. Once applied, all of the rules in that configuration set are applied to the email. Configuration sets can be used to apply the following types of rules to emails:

  • Event publishing – Amazon Simple Email Service can track the number of send, delivery, open, click, bounce, and complaint events for each email sent. Use event publishing to send information about these events to other Amazon Web Services services such as and Amazon CloudWatch.

  • IP pool management – When leasing dedicated IP addresses with Amazon Simple Email Service, you can create groups of IP addresses, called dedicated IP pools. You can then associate the dedicated IP pools with configuration sets.

SmsConfiguration -> (structure)

The SMS configuration.

SnsCallerArn -> (string)

The Amazon Resource Name (ARN) of the Amazon SNS caller. This is the ARN of the IAM role in your Amazon Web Services account that Amazon Cognito will use to send SMS messages. SMS messages are subject to a spending limit .

ExternalId -> (string)

The external ID is a value that you should use to add security to your IAM role that is used to call Amazon SNS to send SMS messages for your user pool. If you provide an ExternalId , the Amazon Cognito User Pool will include it when attempting to assume your IAM role so that you can set your roles trust policy to require the ExternalID . If you use the Amazon Cognito Management Console to create a role for SMS multi-factor authentication (MFA), Amazon Cognito will create 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

UserPoolTags -> (map)

The tags that are assigned to the user pool. A tag is a label that you can apply to user pools to categorize and manage them in different ways, such as by purpose, owner, environment, or other criteria.

key -> (string)

SmsConfigurationFailure -> (string)

The reason why the SMS configuration can’t send the messages to your users.

This message might include comma-separated values to describe why your SMS configuration can’t send messages to user pool end users.

  • InvalidSmsRoleAccessPolicyException - The Identity and Access Management role that Amazon Cognito uses to send SMS messages isn’t properly configured. For more information, see SmsConfigurationType .

  • SNSSandbox - The Amazon Web Services account is in SNS Sandbox and messages will only reach verified end users. This parameter won’t get populated with SNSSandbox if the IAM user creating the user pool doesn’t have SNS permissions. To learn how to move your Amazon Web Services account out of the sandbox, see Moving out of the SMS sandbox .

EmailConfigurationFailure -> (string)

The reason why the email configuration can’t send the messages to your users.

Domain -> (string)

CaseSensitive -> (boolean)

Specifies whether username case sensitivity will be applied for all users in the user pool through Amazon Cognito APIs.

Valid values include:

  • **True ** : Enables case sensitivity for all username input. When this option is set to True , users must sign in using the exact capitalization of their given username, such as “UserName”. This is the default value.

  • **False ** : Enables case insensitivity for all username input. For example, when this option is set to False , users can sign in using either “username” or “Username”. This option also enables both preferred_username and email alias to be case insensitive, in addition to the username attribute.

Arn -> (string)

The Amazon Resource Name (ARN) for the user pool.

AccountRecoverySetting -> (structure)

The available verified method a user can use to recover their password when they call ForgotPassword . You can use this setting to define a preferred method when a user has more than one method available. With this setting, SMS doesn’t qualify for a valid password recovery mechanism if the user also has SMS multi-factor authentication (MFA) activated. In the absence of this setting, Amazon Cognito uses the legacy behavior to determine the recovery method where SMS is preferred through email.

RecoveryMechanisms -> (list)
