macOS Platform Single Sign-On (PSSO)

Apple Platform SSO (PSSO) is a framework provided by Apple, introduced in macOS Ventura, that enables identity providers to integrate with the macOS login experience and system-level authentication. It serves the following purposes:

• Provides Single Sign-On (SSO) for macOS applications and browsers using the same identity provider credentials.
• Integrates with the macOS login window, allowing users to authenticate once and gain access to enterprise resources without repeated prompts.
