This operation provides a mechanism for tying an enterprise identity store or directory to role-based AWS access without user-specific credentials or configuration. For a comparison of <code>AssumeRoleWithSAML</code> with the other APIs that produce temporary credentials, see <a href="http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html">Requesting Temporary Security Credentials</a> and <a href="http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#stsapi_comparison">Comparing the AWS STS APIs</a> in the <i>IAM User Guide</i>. The temporary security credentials returned by this operation 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 AWS services. The temporary security credentials are valid for the duration that you specified when calling <code>AssumeRole</code>, or until the time specified in the SAML authentication response's <code>SessionNotOnOrAfter</code> value, whichever is shorter. The duration can be from 900 seconds (15 minutes) to a maximum of 3600 seconds (1 hour). The default is 1 hour. The temporary security credentials created by <code>AssumeRoleWithSAML</code> can be used to make API calls to any AWS service with the following exception: you cannot call the STS service's <code>GetFederationToken</code> or <code>GetSessionToken</code> APIs. Optionally, you can pass an IAM access policy to this operation. If you choose not to pass a policy, the temporary security credentials that are returned by the operation have the permissions that are defined in the access policy of the role that is being assumed. If you pass a policy to this operation, the temporary security credentials that are returned by the operation have the permissions that are allowed by the intersection of both the access policy of the role that is being assumed, <i><b>and</b></i> the policy that you pass. This means that both policies must grant the permission for the action to be allowed. This gives you a way to further restrict the permissions for the resulting temporary security credentials. You cannot use the passed policy to grant permissions that are in excess of those allowed by the access policy of the role that is being assumed. For more information, see <a href="http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_assumerole.html">Permissions for AssumeRole, AssumeRoleWithSAML, and AssumeRoleWithWebIdentity</a> in the <i>IAM User Guide</i>. Before your application can call <code>AssumeRoleWithSAML</code>, you must configure your SAML identity provider (IdP) to issue the claims required by AWS. Additionally, you must use AWS Identity and Access Management (IAM) to create a SAML provider entity in your AWS account that represents your identity provider, and create an IAM role that specifies this SAML provider in its trust policy. Calling <code>AssumeRoleWithSAML</code> does not require the use of AWS security credentials. The identity of the caller is validated by using keys in the metadata document that is uploaded for the SAML provider entity for your identity provider. <important><para> Calling <code>AssumeRoleWithSAML</code> can result in an entry in your AWS CloudTrail logs. The entry includes the value in the <code>NameID</code> element of the SAML assertion. We recommend that you use a NameIDType that is not associated with any personally identifiable information (PII). For example, you could instead use the Persistent Identifier (<code>urn:oasis:names:tc:SAML:2.0:nameid-format:persistent</code>). </para></important> For more information, see the following resources: - <a href="http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_saml.html">About SAML 2.0-based Federation</a> in the <i>IAM User Guide</i>. - <a href="http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_create_saml.html">Creating SAML Identity Providers</a> in the <i>IAM User Guide</i>. - <a href="http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_create_saml_relying-party.html">Configuring a Relying Party and Claims</a> in the <i>IAM User Guide</i>. - <a href="http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create_for-idp_saml.html">Creating a Role for SAML 2.0 Federation</a> in the <i>IAM User Guide</i>. </para> </description> <syntax> <syntaxItem> <name>Use-STSRoleWithSAML</name> <parameter required="False" variableLength="false" globbing="false" pipelineInput="True (ByValue, )" position="1"> <name>RoleArn</name> <description> <para>The Amazon Resource Name (ARN) of the role that the caller is assuming. </para> </description> <parameterValue required="true" variableLength="false">System.String</parameterValue> </parameter> <parameter required="False" variableLength="false" globbing="false" pipelineInput="False" position="2"> <name>PrincipalArn</name> <description> <para>The Amazon Resource Name (ARN) of the SAML provider in IAM that describes the IdP. </para> </description> <parameterValue required="true" variableLength="false">System.String</parameterValue> </parameter> <parameter required="False" variableLength="false" globbing="false" pipelineInput="False" position="3"> <name>SAMLAssertion</name> <description> <para>The base-64 encoded SAML authentication response provided by the IdP.

Therefore, you can distribute an application (for example, on mobile devices) that requests temporary security credentials without including long-term AWS credentials in the application or by deploying server-based proxy services that use long-term AWS credentials. For more information, see Creating a Mobile Application with Third-Party Sign-In in <i>AWS Security Token Service</i> . The temporary security credentials 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 AWS service APIs. The credentials are valid for the duration that you specified when calling <c>AssumeRoleWithWebIdentity</c> , which can be from 900 seconds (15 minutes) to 3600 seconds (1 hour). By default, the temporary security credentials are valid for 1 hour. The temporary security credentials that are returned from the <c>AssumeRoleWithWebIdentity</c> response have the permissions that are associated with the access policy of the role being assumed and any policies that are associated with the AWS resource being accessed. You can further restrict the permissions of the temporary security credentials by passing a policy in the request. The resulting permissions are an intersection of both policies. The role's access policy and the policy that you passed are evaluated when calls to AWS service APIs are made using the temporary security credentials. Before your application can call <c>AssumeRoleWithWebIdentity</c> , you must have an identity token from an identity provider and create a role that the application can assume. Typically, to get an identity token, you need to register your application with the identity provider and get a unique application ID from that provider. Also, when you create the role that the application assumes, you must specify the registered identity provider as a principal (establish trust with the identity provider).

For example, if a user is not authorized to perform an operation that he or she has requested, the request returns a <code>Client.UnauthorizedOperation</code> response (an HTTP 403 response). Some AWS operations additionally return an encoded message that can provide details about this authorization failure. Only certain AWS operations return an encoded authorization message. The documentation for an individual operation indicates whether that operation returns an encoded message in addition to returning an HTTP code. The message is encoded because the details of the authorization status can constitute privileged information that the user who requested the operation should not see. To decode an authorization status message, a user must be granted permissions via an IAM policy to request the <code>DecodeAuthorizationMessage</code> (<code>sts:DecodeAuthorizationMessage</code>) action. The decoded message includes the following type of information: - Whether the request was denied due to an explicit deny or due to the absence of an explicit allow.

For more information about access keys, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html">Managing Access Keys for IAM Users</a> in the <i>IAM User Guide</i>. When you pass an access key ID to this operation, it returns the ID of the AWS account to which the keys belong. Access key IDs beginning with <code>AKIA</code> are long-term credentials for an IAM user or the AWS account root user. Access key IDs beginning with <code>ASIA</code> are temporary credentials that are created using STS operations. If the account in the response belongs to you, you can sign in as the root user and review your root user access keys. Then, you can pull a <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_getting-report.html">credentials report</a> to learn which IAM user owns the keys. To learn who requested the temporary credentials for an <code>ASIA</code> access key, view the STS events in your <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/cloudtrail-integration.html">CloudTrail logs</a>. This operation does not indicate the state of the access key. The key might be active, inactive, or deleted. Active keys might not have permissions to perform an operation.

A typical use is in a proxy application that gets temporary security credentials on behalf of distributed applications inside a corporate network. You must call the <code>GetFederationToken</code> operation using the long-term security credentials of an IAM user. As a result, this call is appropriate in contexts where those credentials can be safely stored, usually in a server-based application. For a comparison of <code>GetFederationToken</code> with the other API operations that produce temporary credentials, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html">Requesting Temporary Security Credentials</a> and <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#stsapi_comparison">Comparing the AWS STS API operations</a> in the <i>IAM User Guide</i>. You can create a mobile-based or browser-based app that can authenticate users using a web identity provider like Login with Amazon, Facebook, Google, or an OpenID Connect-compatible identity provider. In this case, we recommend that you use <a href="http://aws.amazon.com/cognito/">Amazon Cognito</a> or <code>AssumeRoleWithWebIdentity</code>. For more information, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_assumerolewithwebidentity">Federation Through a Web-based Identity Provider</a>. You can also call <code>GetFederationToken</code> using the security credentials of an AWS account root user, but we do not recommend it. Instead, we recommend that you create an IAM user for the purpose of the proxy application. Then attach a policy to the IAM user that limits federated users to only the actions and resources that they need to access. For more information, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html">IAM Best Practices</a> in the <i>IAM User Guide</i>. The temporary credentials are valid for the specified duration, from 900 seconds (15 minutes) up to a maximum of 129,600 seconds (36 hours). The default is 43,200 seconds (12 hours). Temporary credentials that are obtained by using AWS account root user credentials have a maximum duration of 3,600 seconds (1 hour). The temporary security credentials created by <code>GetFederationToken</code> can be used to make API calls to any AWS service with the following exceptions: - You cannot use these credentials to call any IAM API operations. - You cannot call any STS API operations except <code>GetCallerIdentity</code>. <b>Permissions</b> You must pass an inline or managed <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session">session policy</a> 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 plain text that you use for both inline and managed session policies shouldn't exceed 2048 characters. Though the session policy parameters are optional, if you do not pass a policy, then the resulting federated user session has no permissions. The only exception is when the credentials are used to access a resource that has a resource-based policy that specifically references the federated user session in the <code>Principal</code> element of the policy. When you pass session policies, the session permissions are the intersection of the IAM user policies and the session policies that you pass. This gives you a way to further restrict the permissions for a federated user. You cannot use session policies to grant more permissions than those that are defined in the permissions policy of the IAM user.

The credentials consist of an access key ID, a secret access key, and a security token. Typically, you use <code>GetSessionToken</code> if you want to use MFA to protect programmatic calls to specific AWS API operations like Amazon EC2 <code>StopInstances</code>. MFA-enabled IAM users would need to call <code>GetSessionToken</code> and submit an MFA code that is associated with their MFA device. Using the temporary security credentials that are returned from the call, IAM users can then make programmatic calls to API operations that require MFA authentication. If you do not supply a correct MFA code, then the API returns an access denied error. For a comparison of <code>GetSessionToken</code> with the other API operations that produce temporary credentials, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html">Requesting Temporary Security Credentials</a> and <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#stsapi_comparison">Comparing the AWS STS API operations</a> in the <i>IAM User Guide</i>. The <code>GetSessionToken</code> operation must be called by using the long-term AWS security credentials of the AWS account root user or an IAM user. Credentials that are created by IAM users are valid for the duration that you specify. This duration can range from 900 seconds (15 minutes) up to a maximum of 129,600 seconds (36 hours), with a default of 43,200 seconds (12 hours). Credentials based on account credentials can range from 900 seconds (15 minutes) up to 3,600 seconds (1 hour), with a default of 1 hour. The temporary security credentials created by <code>GetSessionToken</code> can be used to make API calls to any AWS service with the following exceptions: - You cannot call any IAM API operations unless MFA authentication information is included in the request. - You cannot call any STS API <i>except</i><code>AssumeRole</code> or <code>GetCallerIdentity</code>. We recommend that you do not call <code>GetSessionToken</code> with AWS account root user credentials. Instead, follow our <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#create-iam-users">best practices</a> by creating one or more IAM users, giving them the necessary permissions, and using IAM users for everyday interaction with AWS. The credentials that are returned by <code>GetSessionToken</code> are based on permissions associated with the user whose credentials were used to call the operation. If <code>GetSessionToken</code> is called using AWS account root user credentials, the temporary credentials have root user permissions. Similarly, if <code>GetSessionToken</code> is called using the credentials of an IAM user, the temporary credentials have the same permissions as the IAM user.

These temporary credentials consist of an access key ID, a secret access key, and a security token. Typically, you use <code>AssumeRole</code> within your account or for cross-account access. For a comparison of <code>AssumeRole</code> with other API operations that produce temporary credentials, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html">Requesting Temporary Security Credentials</a> and <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#stsapi_comparison">Comparing the AWS STS API operations</a> in the <i>IAM User Guide</i>. <important><para> You cannot use AWS account root user credentials to call <code>AssumeRole</code>. You must use credentials for an IAM user or an IAM role to call <code>AssumeRole</code>. </para></important> For cross-account access, imagine that you own multiple accounts and need to access resources in each account. You could create long-term credentials in each account to access those resources. However, managing all those credentials and remembering which one can access which account can be time consuming. Instead, you can create one set of long-term credentials in one account. Then use temporary security credentials to access all the other accounts by assuming roles in those accounts. For more information about roles, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html">IAM Roles</a> in the <i>IAM User Guide</i>. By default, the temporary security credentials created by <code>AssumeRole</code> last for one hour. However, you can use the optional <code>DurationSeconds</code> 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 <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html#id_roles_use_view-role-max-session">View the Maximum Session Duration Setting for a Role</a> in the <i>IAM User Guide</i>. The maximum session duration limit applies when you use the <code>AssumeRole*</code> API operations or the <code>assume-role*</code> CLI commands. However the limit does not apply when you use those operations to create a console URL. For more information, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html">Using IAM Roles</a> in the <i>IAM User Guide</i>. The temporary security credentials created by <code>AssumeRole</code> can be used to make API calls to any AWS service with the following exception: You cannot call the AWS STS <code>GetFederationToken</code> or <code>GetSessionToken</code> API operations. (Optional) You can pass inline or managed <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session">session policies</a> 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 plain text that you use for both inline and managed session policies shouldn't exceed 2048 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 AWS 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 <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session">Session Policies</a> in the <i>IAM User Guide</i>. To assume a role from a different account, your AWS account must be trusted by the role. The trust relationship is defined in the role's trust policy when the role is created. That trust policy states which accounts are allowed to delegate that access to users in the account. A user who wants to access a role in a different account must also have permissions that are delegated from the user account administrator. The administrator must attach a policy that allows the user to call <code>AssumeRole</code> for the ARN of the role in the other account. If the user is in the same account as the role, then you can do either of the following: - Attach a policy to the user (identical to the previous user in a different account). - Add the user as a principal directly in the role's trust policy. In this case, the trust policy acts as an IAM resource-based policy. Users in the same account as the role do not need explicit permission to assume the role. For more information about trust policies and resource-based policies, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html">IAM Policies</a> in the <i>IAM User Guide</i>. <b>Using MFA with AssumeRole</b> (Optional) You can include multi-factor authentication (MFA) information when you call <code>AssumeRole</code>. This is useful for cross-account scenarios to ensure that the user that assumes the role has been authenticated with an AWS MFA device. In that scenario, the trust policy of the role being assumed includes a condition that tests for MFA authentication. If the caller does not include valid MFA information, the request to assume the role is denied. The condition in a trust policy that tests for MFA authentication might look like the following example. <code>"Condition": {"Bool": {"aws:MultiFactorAuthPresent": true}}</code> For more information, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/MFAProtectedAPI.html">Configuring MFA-Protected API Access</a> in the <i>IAM User Guide</i> guide. To use MFA with <code>AssumeRole</code>, you pass values for the <code>SerialNumber</code> and <code>TokenCode</code> parameters. The <code>SerialNumber</code> value identifies the user's hardware or virtual MFA device. The <code>TokenCode</code> is the time-based one-time password (TOTP) that the MFA device produces. </para> </description> <syntax> <syntaxItem> <name>Use-STSRole</name> <parameter required="False" variableLength="false" globbing="false" pipelineInput="True (ByValue, )" position="1"> <name>RoleArn</name> <description> <para>The Amazon Resource Name (ARN) of the role to assume. </para> </description> <parameterValue required="true" variableLength="false">System.String</parameterValue> </parameter> <parameter required="False" variableLength="false" globbing="false" pipelineInput="False" position="2"> <name>RoleSessionName</name> <description> <para>An identifier for the assumed role session.

You can use the role's temporary credentials in subsequent AWS 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 <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session">Session Policies</a> in the <i>IAM User Guide</i>. The plain text that you use for both inline and managed session policies shouldn't exceed 2048 characters. The JSON policy characters can be any ASCII character from the space character to the end of the valid character list (\u0020 through \u00FF). It can also include the tab (\u0009), linefeed (\u000A), and carriage return (\u000D) characters. The characters in this parameter count towards the 2048 character session policy guideline. However, an AWS conversion compresses the session policies into a packed binary format that has a separate limit. This is the enforced limit. The <code>PackedPolicySize</code> response element indicates by percentage how close the policy is to the upper size limit. </para> </description> <parameterValue required="true" variableLength="false">System.String</parameterValue> <type> <name>System.String</name> <uri /> </type> <defaultValue>None</defaultValue> </parameter> <parameter required="False" variableLength="false" globbing="false" pipelineInput="False" position="Named"> <name>PolicyArn</name> <description> <para>The Amazon Resource Names (ARNs) of the IAM managed policies that you want to use as managed session policies.

Use the role session name to uniquely identify a session when the same role is assumed by different principals or for different reasons. In cross-account scenarios, the role session name is visible to, and can be logged by the account that owns the role. The role session name is also used in the ARN of the assumed role principal. This means that subsequent cross-account API requests that use the temporary security credentials will expose the role session name to the external account in their AWS CloudTrail logs.
