AdminListDevices

Lists a user's registered devices. Remembered devices are used in authentication services where you offer a "Remember me" option for users who you want to permit to sign in without MFA from a trusted device. Users can bypass MFA while your application performs device SRP authentication on the back end. For more information, see Working with devices.

Note

Amazon Cognito evaluates AWS 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.

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.

Limit

The maximum number of devices that you want Amazon Cognito to return in the response.

Type: Integer

Valid Range: Minimum value of 0. Maximum value of 60.

Required: No

PaginationToken

This API operation returns a limited number of results. The pagination token is an identifier that you can present in an additional API request with the same parameters. When you include the pagination token, Amazon Cognito returns the next set of items after the current list. Subsequent requests return a new pagination token. By use of this token, you can paginate through the full list of items.

Type: String

Length Constraints: Minimum length of 1.

Pattern: [\S]+

Required: No

Username

The name of the user that you want to query or modify. The value of this parameter is typically your user's username, but it can be any of their alias attributes. If username isn't an alias attribute in your user pool, this value must be the sub of a local user or the username of a user from a third-party IdP.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: [\p{L}\p{M}\p{S}\p{N}\p{P}]+

Required: Yes

UserPoolId

The ID of the user pool where the device owner is a user.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 55.

Pattern: [\w-]+_[0-9a-zA-Z]+

Required: Yes
