OIDC vs SAML: Which Protocol to Use?

Authentication protocols like SAML and OIDC are fundamental to managing user access in applications, each offering distinct advantages based on system needs. SAML, with its XML-based assertions and certificate exchanges, is widely used in enterprise environments for single sign-on and federated identity management, though it is complex to implement. OIDC, on the other hand, is a modern, lightweight protocol based on OAuth 2.0, utilizing JSON Web Tokens and REST-based endpoints, making it suitable for single-page applications, mobile apps, and APIs. SuperTokens supports OIDC natively, facilitating integration with providers such as Google and Azure AD, while SAML can be incorporated through a bridging service like SAML Jackson. This flexibility allows developers to choose the most fitting protocol for their environment, ensuring unified session management and compliance with organizational requirements. Both protocols are secure when implemented correctly, and SuperTokens provides a consistent session handling experience regardless of the chosen protocol, catering to both modern and legacy systems.
