ConfirmDevice - Amazon Cognito User Pools
이 페이지는 귀하의 언어로 번역되지 않았습니다. 번역 요청

ConfirmDevice

Confirms a device that a user wants to remember. A remembered device is a "Remember me on this device" option for user pools that perform authentication with the device key of a trusted device in the back end, instead of a user-provided MFA code. For more information about device authentication, see Working with user devices in your user pool.

Authorize this action with a signed-in user's access token. It must include the scope aws.cognito.signin.user.admin.

Note

Amazon Cognito doesn't evaluate AWS Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you can't use IAM credentials to authorize requests, and you can't grant IAM permissions in policies. For more information about authorization models in Amazon Cognito, see Using the Amazon Cognito user pools API and user pool endpoints.

Request Syntax

{ "AccessToken": "string", "DeviceKey": "string", "DeviceName": "string", "DeviceSecretVerifierConfig": { "PasswordVerifier": "string", "Salt": "string" } }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Type: String

Pattern: [A-Za-z0-9-_=.]+

Required: Yes

DeviceKey

The unique identifier, or device key, of the device that you want to update the status for.

Type: String

Response Syntax

{ "UserConfirmationNecessary": boolean }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

UserConfirmationNecessary

When true, your user must confirm that they want to remember the device. Prompt the user for an answer.

You must then make an UpdateDeviceStatus request that sets the device to remembered or not_remembered.

When false, immediately sets the device as remembered and eligible for device authentication.

You can configure your user pool to always remember devices, in which case this response is false, or to allow users to opt in, in which case this response is true. Configure this option under Device tracking in the Sign-in menu of your user pool.

You can also configure this option with the DeviceConfiguration parameter of a CreateUserPool or UpdateUserPool request.

Type: Boolean
