Introduction
Single sign-on (SSO) provides a seamless way for your add-in to authenticate users. Using this method, your add-in can authenticate the user to retrieve identity information or to obtain from another secured endpoint such as Microsoft Graph. To do this, your add-in must call a server-side web API registered with Microsoft Entra ID.
In this module, you'll learn how to implement SSO for your Office Add-ins.
