Enable single sign-on for an enterprise application

In this article, you use the Microsoft Entra admin center to enable single sign-on (SSO) for an enterprise application that you added to your Microsoft Entra tenant. After you configure SSO, your users can sign in by using their Microsoft Entra credentials.

Microsoft Entra ID has a gallery that contains thousands of preintegrated applications that use SSO. This article uses an enterprise application named Microsoft Entra SAML Toolkit 1 as an example, but the concepts apply for most preconfigured enterprise applications in the Microsoft Entra application gallery.

It's recommended that you use a nonproduction environment to test the steps in this article.
