/**
 * <p>Returns a set of temporary credentials for an Amazon Web Services account or 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 Amazon Web Services API operations like Amazon EC2
 *          <code>StopInstances</code>.</p>
 *          <p>MFA-enabled IAM users must call <code>GetSessionToken</code> and submit
 *          an MFA code that is associated with their MFA device. Using the temporary security
 *          credentials that the call returns, IAM users can then make programmatic
 *          calls to API operations that require MFA authentication. An incorrect MFA code causes the
 *          API to return 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
 *             Amazon Web Services STS API operations</a> in the <i>IAM User Guide</i>.</p>
 *          <note>
 *             <p>No permissions are required for users to perform this operation. The purpose of the
 *                <code>sts:GetSessionToken</code> operation is to authenticate the user using MFA. You
 *             cannot use policies to control authentication operations. For more information, see
 *                <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_getsessiontoken.html">Permissions for GetSessionToken</a> in the
 *             <i>IAM User Guide</i>.</p>
 *          </note>
 *          <p>
 *             <b>Session Duration</b>
 *          </p>
 *          <p>The <code>GetSessionToken</code> operation must be called by using the long-term Amazon Web Services
 *          security credentials of 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. </p>
 *          <p>
 *             <b>Permissions</b>
 *          </p>
 *          <p>The temporary security credentials created by <code>GetSessionToken</code> can be used
 *          to make API calls to any Amazon Web Services service with the following exceptions:</p>
 *          <ul>
 *             <li>
 *                <p>You cannot call any IAM API operations unless MFA authentication information is
 *                included in the request.</p>
 *             </li>
 *             <li>
 *                <p>You cannot call any STS API <i>except</i>
 *                   <code>AssumeRole</code> or <code>GetCallerIdentity</code>.</p>
 *             </li>
 *          </ul>
 *          <p>The credentials that <code>GetSessionToken</code> returns are based on permissions
 *          associated with the IAM user whose credentials were used to call the
 *          operation. The temporary credentials have the same permissions as the IAM user.</p>
 *          <note>
 *             <p>Although it is possible to call <code>GetSessionToken</code> using the security
 *             credentials of an Amazon Web Services account root user rather than an IAM user, we do
 *             not recommend it. If <code>GetSessionToken</code> is called using root user
 *             credentials, the temporary credentials have root user permissions. For more
 *             information, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#lock-away-credentials">Safeguard your root user credentials and don't use them for everyday tasks</a> in the
 *                <i>IAM User Guide</i>
 *             </p>
 *          </note>
 *          <p>For more information about using <code>GetSessionToken</code> to create temporary
 *          credentials, see <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_getsessiontoken">Temporary
 *             Credentials for Users in Untrusted Environments</a> in the
 *             <i>IAM User Guide</i>. </p>
