--policies (structure)

A container with the policies you wish to update in a user pool.

PasswordPolicy -> (structure)

The password policy.

MinimumLength -> (integer)

The minimum length of the password policy that you have set. Cannot be less than 6.

RequireUppercase -> (boolean)

In the password policy that you have set, refers to whether you have required users to use at least one uppercase letter in their password.

--email-configuration (structure)

Email configuration.

SourceArn -> (string)

The Amazon Resource Name (ARN) of a verified email address in Amazon SES. This email address is used 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 by 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 to.

EmailSendingAccount -> (string)

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


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 below 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 Amazon Cognito in the Amazon Cognito Developer Guide .

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


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 AWS 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 IAM role, in your AWS account. This role contains the permissions that allow Amazon Cognito 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)

Identifies 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 will appear before the body of the email.

ConfigurationSet -> (string)

The set of configuration rules that can be applied to emails sent using Amazon SES. 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 SES 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 AWS services such as SNS and CloudWatch.

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

Shorthand Syntax:


JSON Syntax:

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

--sms-configuration (structure)

SMS configuration.

SnsCallerArn -> (string)

The Amazon Resource Name (ARN) of the Amazon Simple Notification Service (SNS) caller. This is the ARN of the IAM role in your AWS account which Cognito will use to send SMS messages.

ExternalId -> (string)

The external ID is a value that we recommend you use to add security to your IAM role which is used to call Amazon SNS to send SMS messages for your user pool. If you provide an ExternalId , the 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 Cognito Management Console to create a role for SMS MFA, Cognito will create a role with the required permissions and a trust policy that demonstrates use of the ExternalId .

Shorthand Syntax:


JSON Syntax:

  "SnsCallerArn": "string",
  "ExternalId": "string"

--user-pool-tags (map)

The tag keys and values to assign to the user pool. A tag is a label that you can use to categorize and manage user pools in different ways, such as by purpose, owner, environment, or other criteria.

key -> (string)

value -> (string)

Shorthand Syntax:


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.


If you set a value for TemporaryPasswordValidityDays in PasswordPolicy , that value will be used and UnusedAccountValidityDays will be deprecated 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.

EmailMessage -> (string)

AdvancedSecurityMode -> (string)

The advanced security mode.

Shorthand Syntax:


JSON Syntax:

  "AdvancedSecurityMode": "OFF"|"AUDIT"|"ENFORCED"

--account-recovery-setting (structure)

Use this setting to define which verified available method a user can use to recover their password when they call ForgotPassword . It allows you to define a preferred method when a user has more than one method available. With this setting, SMS does not qualify for a valid password recovery mechanism if the user also has SMS MFA enabled. In the absence of this setting, Cognito uses the legacy behavior to determine the recovery method where SMS is preferred over email.

RecoveryMechanisms -> (list)

The list of RecoveryOptionTypes .


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)

Specifies the recovery method for a user.

Shorthand Syntax:


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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.
