Configure the session duration of the AWS access portal and IAM Identity Center integrated applications - AWS IAM Identity Center

Configure the session duration of the AWS access portal and IAM Identity Center integrated applications

The session duration of authentication into the AWS access portal and IAM Identity Center integrated applications is the maximum length of time that a user can be signed in without re-authenticating. The default session duration is 8 hours. The IAM Identity Center Administrator can specify a different duration, from a minimum of 15 minutes to a maximum of 90 days. For more information about authentication session duration and user behavior, see Authentication.

The following topics provide information about configuring the session duration of the AWS access portal and IAM Identity Center integrated applications.

Prerequisites and considerations

The following are the prerequisites and considerations for configuring the session duration for the AWS access portal and IAM Identity Center integrated applications.

External identity providers

IAM Identity Center uses SessionNotOnOrAfter attribute from SAML assertions to help determine how long the session can be valid for.

  • If SessionNotOnOrAfter is not passed in a SAML assertion, the duration of an AWS access portal session is not impacted by the duration of your external IdP session. For example, if your IdP session duration is 24 hours and you set an 18-hour session duration in IAM Identity Center, your users must re-authenticate in the AWS access portal after 18 hours.

  • If SessionNotOnOrAfter is passed in a SAML assertion, the session duration value is set to the shorter of the AWS access portal session duration and your SAML IdP session duration. If you set a 72-hour session duration in IAM Identity Center and your IdP has a session duration of 18 hours, your users will have access to AWS resources for the 18 hours defined in your IdP.

  • If the session duration of your IdP is longer than the one set in IAM Identity Center, your users will be able to start a new IAM Identity Center session without re-entering their credentials, based on their still-valid login session with your IdP.

Note

If you're using Active Directory as an identity source for IAM Identity Center, session management isn't supported.

AWS CLI and SDK sessions

If you're using the AWS Command Line Interface, AWS Software Development Kits (SDKs), or other AWS development tools to access AWS services programmatically, the following prerequisites must be met to set session duration for the AWS access portal and the IAM Identity Center integrated applications.

  • You must configure the AWS access portal session duration in the IAM Identity Center console.

  • You must define a profile for single sign-on settings in your shared AWS config file. This profile is used to connect to the AWS access portal. We recommend that you use the SSO token provider configuration. With this configuration, your AWS SDK or tool can automatically retrieve refreshed authentication tokens. For more information, see SSO token provider configuration in the AWS SDK and Tools Reference Guide.

  • Users must run a version of the AWS CLI or an SDK that supports session management.

Minimum versions of the AWS CLI that support session management

Following are the minimum versions of the AWS CLI that support session management.

  • AWS CLI V2 2.9 or later

  • AWS CLI V1 1.27.10 or later

For information about how to install or update the latest AWS CLI version, see Installing or updating the latest version of the AWS CLI.

If your users are running the AWS CLI, if you refresh your permission set just before the IAM Identity Center session is set to expire and the session duration is set to 20 hours while the permission set duration is set to 12 hours, the AWS CLI session runs for the maximum of 20 hours plus 12 hours for a total of 32 hours. For more information about the IAM Identity Center CLI, see AWS CLI Command Reference.

How to configure the session duration

Use the following procedure to configure the session duration of the AWS access portal and IAM Identity Center integrated applications.

  1. Open the IAM Identity Center console.

  2. Choose Settings.

  3. On the Settings page, choose the Authentication tab.

  4. Under Authentication, next to Session settings, choose Configure. A Configure session settings dialog box appears.

  5. In the Configure session settings dialog box, choose the maximum session duration in minutes, hours, and days for your users by selecting the drop down arrow. Choose a the length for the session, and then choose Save. You return to the Settings page.
