Container for the parameters to the CreateUserPool operation.

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 US phone numbers. If you use SMS text messages in Amazon Cognito, you must register a phone number with Amazon Pinpoint. Amazon Cognito uses the registered number automatically. Otherwise, Amazon Cognito users who must receive SMS messages might not be able 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 the SMS sandbox. In sandbox mode, you can send messages only to verified phone numbers. After you test your app while in the sandbox environment, you can move out of the sandbox and into production. For more information, see SMS message settings for Amazon Cognito user pools in the Amazon Cognito Developer Guide.

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

If you don't provide a value for an attribute, Amazon Cognito sets it to its default value.

Amazon Cognito evaluates Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you must use IAM credentials to authorize requests, and you must grant yourself the corresponding IAM permission in a policy.

Constructors

NameDescription
Public Method CreateUserPoolRequest()

Properties

NameTypeDescription
Public Property AccountRecoverySetting Amazon.CognitoIdentityProvider.Model.AccountRecoverySettingType

Gets and sets the property AccountRecoverySetting.

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.

Public Property AdminCreateUserConfig Amazon.CognitoIdentityProvider.Model.AdminCreateUserConfigType

Gets and sets the property AdminCreateUserConfig.

The configuration for AdminCreateUser requests.

Public Property AliasAttributes System.Collections.Generic.List<System.String>

Gets and sets the property AliasAttributes.

Attributes supported as an alias for this user pool. Possible values: phone_number, email, or preferred_username.

Public Property AutoVerifiedAttributes System.Collections.Generic.List<System.String>

Gets and sets the property AutoVerifiedAttributes.

The attributes to be auto-verified. Possible values: email, phone_number.

Public Property DeletionProtection Amazon.CognitoIdentityProvider.DeletionProtectionType

Gets and sets the property DeletionProtection.

When active, DeletionProtection prevents accidental deletion of your user pool. Before you can delete a user pool that you have protected against deletion, you must deactivate this feature.

When you try to delete a protected user pool in a DeleteUserPool API request, Amazon Cognito returns an InvalidParameterException error. To delete a protected user pool, send a new DeleteUserPool request after you deactivate deletion protection in an UpdateUserPool API request.

Public Property DeviceConfiguration Amazon.CognitoIdentityProvider.Model.DeviceConfigurationType

Gets and sets the property DeviceConfiguration.

The device-remembering configuration for a user pool. A null value indicates that you have deactivated device remembering in your user pool.

When you provide a value for any DeviceConfiguration field, you activate the Amazon Cognito device-remembering feature.

Public Property EmailConfiguration Amazon.CognitoIdentityProvider.Model.EmailConfigurationType

Gets and sets the property EmailConfiguration.

The email configuration of your user pool. The email configuration type sets your preferred sending method, Amazon Web Services Region, and sender for messages from your user pool.

Public Property EmailVerificationMessage System.String

Gets and sets the property EmailVerificationMessage.

This parameter is no longer used. See VerificationMessageTemplateType.

Public Property EmailVerificationSubject System.String

Gets and sets the property EmailVerificationSubject.

This parameter is no longer used. See VerificationMessageTemplateType.

Public Property LambdaConfig Amazon.CognitoIdentityProvider.Model.LambdaConfigType

Gets and sets the property LambdaConfig.

The Lambda trigger configuration information for the new user pool.

In a push model, event sources (such as Amazon S3 and custom applications) need permission to invoke a function. So you must make an extra call to add permission for these event sources to invoke your Lambda function.

For more information on using the Lambda API to add permission, see AddPermission .

For adding permission using the CLI, see add-permission .

Public Property MfaConfiguration Amazon.CognitoIdentityProvider.UserPoolMfaType

Gets and sets the property MfaConfiguration.

Specifies MFA configuration details.

Public Property Policies Amazon.CognitoIdentityProvider.Model.UserPoolPolicyType

Gets and sets the property Policies.

The policies associated with the new user pool.

Public Property PoolName System.String

Gets and sets the property PoolName.

A string used to name the user pool.

Public Property Schema System.Collections.Generic.List<Amazon.CognitoIdentityProvider.Model.SchemaAttributeType>

Gets and sets the property Schema.

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

Public Property SmsAuthenticationMessage System.String

Gets and sets the property SmsAuthenticationMessage.

A string representing the SMS authentication message.

Public Property SmsConfiguration Amazon.CognitoIdentityProvider.Model.SmsConfigurationType

Gets and sets the property SmsConfiguration.

The SMS configuration with 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.

Public Property SmsVerificationMessage System.String

Gets and sets the property SmsVerificationMessage.

This parameter is no longer used. See VerificationMessageTemplateType.

Public Property UserAttributeUpdateSettings Amazon.CognitoIdentityProvider.Model.UserAttributeUpdateSettingsType

Gets and sets the property UserAttributeUpdateSettings.

The settings for updates to user attributes. These settings include the property AttributesRequireVerificationBeforeUpdate, a user-pool setting that tells Amazon Cognito how to handle changes to the value of your users' email address and phone number attributes. For more information, see Verifying updates to email addresses and phone numbers.

Public Property UsernameAttributes System.Collections.Generic.List<System.String>

Gets and sets the property UsernameAttributes.

Specifies whether a user can use an email address or phone number as a username when they sign up.

Public Property UsernameConfiguration Amazon.CognitoIdentityProvider.Model.UsernameConfigurationType

Gets and sets the property UsernameConfiguration.

Case sensitivity on the username input for the selected sign-in option. When case sensitivity is set to False (case insensitive), users can sign in with any combination of capital and lowercase letters. For example, username, USERNAME, or UserName, or for email, email@example.com or EMaiL@eXamplE.Com. For most use cases, set case sensitivity to False (case insensitive) as a best practice. When usernames and email addresses are case insensitive, Amazon Cognito treats any variation in case as the same user, and prevents a case variation from being assigned to the same attribute for a different user.

This configuration is immutable after you set it. For more information, see UsernameConfigurationType.

Public Property UserPoolAddOns Amazon.CognitoIdentityProvider.Model.UserPoolAddOnsType

Gets and sets the property UserPoolAddOns.

User pool add-ons. Contains settings for activation of advanced security features. To log user security information but take no action, set to AUDIT. To configure automatic security responses to risky traffic to your user pool, set to ENFORCED.

For more information, see Adding advanced security to a user pool.

Public Property UserPoolTags System.Collections.Generic.Dictionary<System.String, System.String>

Gets and sets the property UserPoolTags.

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.

Public Property VerificationMessageTemplate Amazon.CognitoIdentityProvider.Model.VerificationMessageTemplateType

Gets and sets the property VerificationMessageTemplate.

The template for the verification message that the user sees when the app requests permission to access the user's information.

Examples

The following example creates a user pool with all configurable properties set to an example value. The resulting user pool allows sign-in with username or email address, has optional MFA, and has a Lambda function assigned to each possible trigger.
