This podcast primarily discuss Single Sign-On (SSO) and OAuth, two critical authentication and authorization technologies. SSO allows users to access multiple applications with a single login, improving user experience and security management. The texts cover various SSO protocols like SAML and OpenID Connect, alongside best practices for implementation and potential security considerations. Several sources then explore OAuth, detailing its different versions (1.0 and 2.0), grant types, benefits, and common vulnerabilities, emphasizing its role in secure delegated access for applications. Additionally, Identity as a Service (IDaaS) is introduced as a cloud-based solution for managing user identities and access.
