Organization tenancy: the foundation of SSO and B2B data models

The article from Stytch's B2B Auth School series focuses on the concept of organization tenancy as a foundational element for implementing Single Sign-On (SSO) in B2B SaaS applications. Organization tenancy, a form of multi-tenancy, treats organizations as primary data entities, enabling applications to represent complex companies as single customers, manage memberships, customize settings, and structure teams and roles. This architecture ensures secure data isolation and effective resource coordination, which are critical for preventing data leaks between customers. Building org tenancy involves considerations of security, data modeling, org discovery, and customizable authentication settings, all of which are crucial for supporting SSO by linking an organization's members and authentication flows under a unified structure. The article emphasizes that organization tenancy is essential for B2B companies to efficiently manage their customer relationships and facilitate seamless SSO integration.
