 ## Session duration and timeout
 
-To prevent a person from authenticating with your IdP and staying authorized indefinitely, {% data variables.product.product_name %} periodically invalidates the session for each user account with access to {% ifversion ghec or ghae %}your enterprise's resources{% elsif ghes %}{% data variables.location.product_location %}{% endif %}.

-To customize the session duration, you may be able to define the value of the `SessionNotOnOrAfter` attribute on your IdP. If you define a value less than 24 hours, {% data variables.product.product_name %} may prompt people to authenticate every time {% data variables.product.product_name %} initiates a redirect.

+{% data variables.product.product_name %} will support a customized session duration if your IdP provides the option to configure a `SessionNotOnOrAfter` attribute and value{% ifversion ghes %}, and if this attribute is included in SAML responses. If your IdP does not allow a `SessionNotOnOrAfter` attribute, a site administrator can configure a custom SAML session timeout for all users on your instance by using the `ghe-config saml.default-session-expiration [seconds]` command in the administrative shell{% endif %}.

 To prevent authentication errors, we recommend a minimum session duration of 4 hours. For more information, see "[AUTOTITLE](/admin/identity-and-access-management/using-saml-for-enterprise-iam/troubleshooting-saml-authentication#users-are-repeatedly-redirected-to-authenticate)."
