Explore the evolution of access control systems in this 23-minute conference talk that traces the journey from simple admin-only permissions to complex authorization requirements. Follow a fictional project's progression through different access control models, starting with basic role-based access control (RBAC), encountering the challenges of attribute-based access control (ABAC), and discovering how fine-grained authorization (FGA) provides a solution. Learn how OpenFGA's relationship-based model addresses the growing complexity of modern applications while maintaining flexibility and scalability, making it ideal for handling the tangled web of roles, attributes, exceptions, and edge cases that inevitably emerge as application requirements evolve.
