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 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 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>.</p> <p>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. </p> <p>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:</p> <ul> <li> <p>Attach a policy to the user (identical to the previous user in a different account).</p> </li> <li> <p>Add the user as a principal directly in the role's trust policy.</p> </li> </ul> <p>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.

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.</p> <p> <code>"Condition": {"Bool": {"aws:MultiFactorAuthPresent": true}}</code> </p> <p>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.</p> <p>To use MFA with <code>AssumeRole</code>, you pass values for the <code>SerialNumber</code> and <code>TokenCode</code> parameters.

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>.</p> <p> <b>Permissions</b> </p> <p>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.</p> <p>(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 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 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>.</p> <p>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. </p> <p>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:</p> <ul> <li> <p>Attach a policy to the user (identical to the previous user in a different account).</p> </li> <li> <p>Add the user as a principal directly in the role's trust policy.</p> </li> </ul> <p>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>.</p> <p> <b>Tags</b> </p> <p>(Optional) You can pass tag key-value pairs to your session.

For more information about session tags, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html">Passing Session Tags in STS</a> in the <i>IAM User Guide</i>.</p> <p>An administrator must grant you the permissions necessary to pass session tags.

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.</p> <p> <code>"Condition": {"Bool": {"aws:MultiFactorAuthPresent": true}}</code> </p> <p>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.</p> <p>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. </p>

    /// <p>Returns a set of temporary security credentials (consisting of an access key ID, a secret access key, and a security token) for a federated user. 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>.</p> <note> <p>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>.

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>. </p> <p> <b>Session duration</b> </p> <p>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 session duration 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).</p> <p> <b>Permissions</b> </p> <p>You can use the temporary credentials created by <code>GetFederationToken</code> in any AWS service except the following:</p> <ul> <li> <p>You cannot call any IAM operations using the AWS CLI or the AWS API. </p> </li> <li> <p>You cannot call any STS operations except <code>GetCallerIdentity</code>.</p> </li> </ul> <p>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 can't exceed 2,048 characters.</p> <p>Though the session policy parameters are optional, if you do not pass a policy, then the resulting federated user session has no permissions. 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. 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>. For information about using <code>GetFederationToken</code> to create temporary security credentials, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_getfederationtoken">GetFederationToken—Federation Through a Custom Identity Broker</a>. </p> <p>You can use the credentials to access a resource that has a resource-based policy. If that policy specifically references the federated user session in the <code>Principal</code> element of the policy, the session has the permissions allowed by the policy. These permissions are granted in addition to the permissions granted by the session policies.</p> <p> <b>Tags</b> </p> <p>(Optional) You can pass tag key-value pairs to your session. These are called session tags. For more information about session tags, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html">Passing Session Tags in STS</a> in the <i>IAM User Guide</i>.</p> <p>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 <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/tutorial_attribute-based-access-control.html">Tutorial: Using Tags for Attribute-Based Access Control</a> in the <i>IAM User Guide</i>.</p> <p>Tag key–value pairs are not case sensitive, but case is preserved. This means that you cannot have separate <code>Department</code> and <code>department</code> tag keys. Assume that the user that you are federating has the <code>Department</code>=<code>Marketing</code> tag and you pass the <code>department</code>=<code>engineering</code> session tag. <code>Department</code> and <code>department</code> are not saved as separate tags, and the session tag passed in the request takes precedence over the user tag.</p>
