Apple providesSingle Sign-On (SSO) extensionsas the modern method for integrating iOS, iPadOS, and macOS with identity providers. These extensions support standards such as OAuth 2.0 and OpenID Connect, enabling secure and seamless authentication across enterprise apps. Apple Learning materials emphasize that SSO extensions replace legacy solutions like Kerberos plug-ins, providing developers and IT admins with a consistent way to federate identity. Unlike Enrollment SSO, which is used only during enrollment, the broader SSO extensions function across apps and system services. This enables enterprises to deliver a unified authentication experience, reducing password prompts and ensuring security compliance.
