About this course
A practical course about authentication, authorization and identity federation. Learn RBAC, ABAC and ReBAC as application policy models; understand OAuth 2.0, OpenID Connect and SAML 2.0 protocol flows; and implement phishing-resistant authentication with WebAuthn and passkeys. Examples use HTTP, JSON, XML, SQL, JavaScript and Ruby on Rails, with technical diagrams, security checklists and a final multi-tenant SaaS capstone.
