Overview

Microsoft Enterprise Single Sign-On has been limited on Apple iOS/macOS devices until now. The new SSO plug-in for the Microsoft Authenticator App changes everything.

The Microsoft Enterprise SSO plug-in for Apple devices provides single sign-on (SSO) for Microsoft Entra ID accounts across all applications that support Apple's Enterprise Single Sign-On feature.

NOTE (Updated 2026): macOS support for the Microsoft Enterprise SSO plug-in is now generally available (no longer in preview). Use the same extension configuration for both iOS/iPadOS and macOS devices. For macOS, use Extension ID com.microsoft.CompanyPortalMac.ssoextension with Team ID UBF8T346G9.

UPDATE: If your Teams client starts acting strange, try removing your device from being targeted by this policy and reboot the phone.

Requirements

• iOS 16 minimum OS version
• Latest version of Microsoft Authenticator with your identity configured
• Device enrolled with Intune or another MDM
• SSO feature enabled through a device feature policy
