Single Sign On, logins, and URL redirects

Service Portal uses a combination of system properties and script includes to determine how the system handles URL redirects for users logging in to the portal.

Only users who understand single sign on, URL redirects, and the ServiceNow platform should make any changes.

Use the following topics to set up required authentication, default login page, and URL redirects for Service Portal:

If you are using the system property to automatically redirect to your primary IDP, then Service Portal automatically redirects to that IDP. If you have multiple identity providers, Service Portal shows a link on the login page to "Use external login". For more information on SSO and authentication in the platform, see Authentication.
