Returns a set of temporary security credentials for users who have been authenticated in * a mobile or web application with a web identity provider. Example providers include Amazon Cognito, * Login with Amazon, Facebook, Google, or any OpenID Connect-compatible identity * provider.

* *

For mobile applications, we recommend that you use Amazon Cognito. You can use Amazon Cognito with the * Amazon Web Services SDK for iOS Developer Guide and the Amazon Web Services SDK for Android Developer Guide to uniquely * identify a user. You can also supply the user with a consistent identity throughout the * lifetime of an application.

*

To learn more about Amazon Cognito, see Amazon Cognito Overview in * Amazon Web Services SDK for Android Developer Guide and Amazon Cognito Overview in the * Amazon Web Services SDK for iOS Developer Guide.

* *

Calling AssumeRoleWithWebIdentity does not require the use of Amazon Web Services * security credentials. Therefore, you can distribute an application (for example, on mobile * devices) that requests temporary security credentials without including long-term Amazon Web Services * credentials in the application. You also don't need to deploy server-based proxy services * that use long-term Amazon Web Services credentials. Instead, the identity of the caller is validated by * using a token from the web identity provider. For a comparison of * AssumeRoleWithWebIdentity with the other API operations that produce * temporary credentials, see Requesting Temporary Security * Credentials and Comparing the * STS API operations in the IAM User Guide.

*

The temporary security credentials returned by this API consist of an access key ID, a * secret access key, and a security token. Applications can use these temporary security * credentials to sign calls to Amazon Web Services service API operations.

*

* Session Duration *

*

By default, the temporary security credentials created by * AssumeRoleWithWebIdentity last for one hour. However, you can use the * optional DurationSeconds parameter to specify the duration of your session. * You can provide a value from 900 seconds (15 minutes) up to the maximum session duration * setting for the role. This setting can have a value from 1 hour to 12 hours. To learn how * to view the maximum value for your role, see View the * Maximum Session Duration Setting for a Role in the * IAM User Guide. The maximum session duration limit applies when * you use the AssumeRole* API operations or the assume-role* CLI * commands. However the limit does not apply when you use those operations to create a * console URL. For more information, see Using IAM Roles in the * IAM User Guide.

*

* Permissions *

*

The temporary security credentials created by AssumeRoleWithWebIdentity can * be used to make API calls to any Amazon Web Services service with the following exception: you cannot * call the STS GetFederationToken or GetSessionToken API * operations.

*

(Optional) You can pass inline or managed session policies to * this operation. You can pass a single JSON policy document to use as an inline session * policy. You can also specify up to 10 managed policies to use as managed session policies. * The plaintext that you use for both inline and managed session policies can't exceed 2,048 * characters. Passing policies to this operation returns new * temporary credentials. The resulting session's permissions are the intersection of the * role's identity-based policy and the session policies. You can use the role's temporary * credentials in subsequent Amazon Web Services API calls to access resources in the account that owns * the role. You cannot use session policies to grant more permissions than those allowed * by the identity-based policy of the role that is being assumed. For more information, see * Session * Policies in the IAM User Guide.

*

* Tags *

*

(Optional) You can configure your IdP to pass attributes into your web identity token as * session tags. Each session tag consists of a key name and an associated value. For more * information about session tags, see Passing Session Tags in STS in the * IAM User Guide.

*

You can pass up to 50 session tags. The plaintext session tag keys can’t exceed 128 * characters and the values can’t exceed 256 characters. For these and additional limits, see * IAM * and STS Character Limits in the IAM User Guide.

* * *

An Amazon Web Services conversion compresses the passed session policies and session tags into a * packed binary format that has a separate limit. Your request can fail for this limit * even if your plaintext meets the other requirements. The PackedPolicySize * response element indicates by percentage how close the policies and tags for your * request are to the upper size limit. *

* *

You can pass a session tag with the same key as a tag that is * attached to the role. When you do, the session tag overrides the role tag with the same * key.

*

An administrator must grant you the permissions necessary to pass session tags. The * administrator can also create granular permissions to allow you to pass only specific * session tags. For more information, see Tutorial: Using Tags * for Attribute-Based Access Control in the * IAM User Guide.

*

You can set the session tags as transitive. Transitive tags persist during role * chaining. For more information, see Chaining Roles * with Session Tags in the IAM User Guide.

*

* Identities *

*

Before your application can call AssumeRoleWithWebIdentity, you must have * an identity token from a supported identity provider and create a role that the application * can assume. The role that your application assumes must trust the identity provider that is * associated with the identity token. In other words, the identity provider must be specified * in the role's trust policy.

* *

Calling AssumeRoleWithWebIdentity can result in an entry in your * CloudTrail logs. The entry includes the Subject of * the provided web identity token. We recommend that you avoid using any personally * identifiable information (PII) in this field. For example, you could instead use a GUID * or a pairwise identifier, as suggested * in the OIDC specification.

* *

* * @example * Use a bare-bones client and the command you need to make an API call. * ```javascript * import { STSClient, AssumeRoleWithWebIdentityCommand } from "@aws-sdk/client-sts"; // ES Modules import * // const { STSClient, AssumeRoleWithWebIdentityCommand } = require("@aws-sdk/client-sts"); // CommonJS import * const client = new STSClient(config); * const command = new AssumeRoleWithWebIdentityCommand(input); * const response = await client.send(command); * ``` * * @see {@link AssumeRoleWithWebIdentityCommandInput} for command's `input` shape. * @see {@link AssumeRoleWithWebIdentityCommandOutput} for command's `response` shape. * @see {@link STSClientResolvedConfig | config} for command's `input` shape. * */ export declare class AssumeRoleWithWebIdentityCommand extends $Command { readonly input: AssumeRoleWithWebIdentityCommandInput; constructor(input: AssumeRoleWithWebIdentityCommandInput); /** * @internal */ resolveMiddleware(clientStack: MiddlewareStack, configuration: STSClientResolvedConfig, options?: __HttpHandlerOptions): Handler; private serialize; private deserialize; }
