Microsoft Learning: Using Single Sign-On (SSO) with Office Add-ins

This module explains how to use single sign-on in Office Add-ins.

I work with Microsoft Learning to publish & maintain multiple self-paced learning modules related to Microsoft 365. These modules are primarily used as self-paced study resources for developers preparing to take the MS-600 exam, the only prerequisite to achieve the Microsoft 365 Certified: Teams Application Developer Associate certification. This is one of those modules.

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 that’s registered with Microsoft Entra ID.

In this module, you’ll learn how to implement SSO for your Office Add-ins.

Learning objectives

By the end of this module, you’ll be able to:

  • Understand how Office Add-ins can use SSO to call Microsoft Graph
  • Create Word add-in that uses SSO to call Microsoft Graph
  • Create an Excel add-in that uses SSO to call Microsoft Graph
  • Create an Outlook add-in that uses SSO to call Microsoft Graph
