Step-by-step guide to configuring Platform Single Sign-On (PSSO) on macOS. Learn best practices, troubleshooting tips, and how to optimize PSSO settings for your organization's security needs.

Due to being phishing resistant and generally more secure we will show how to setup PSSO with Secure Enclave in Intune. Alternatively you can follow this guide and select one of the other authentication methods.

Before we begin, just a heads up that you can find the official guide by Microsoft here: https://learn.microsoft.com/en-us/mem/intune/configuration/platform-sso-macos#step-1---decide-the-authentication-method

While the article by Microsoft goes in detail about the differences of each method and what to choose when, we will focus on the configuration policy.

Here is the final configuration profile:
