Software applications often require access to data from other services on behalf of their users, and using standards-compliant authentication protocols like OAuth and SAML is crucial for secure and efficient integrations. These standardized protocols have been publicly vetted by experts, ensuring a trusted framework that reduces risk, facilitates transferable learning across projects, and enhances interoperability with other systems. By employing standardized protocols, organizations can leverage existing code libraries, accelerating development and reducing maintenance burdens, while ensuring that edge cases are typically well-handled. This approach not only simplifies onboarding and collaboration but also provides peace of mind by aligning with industry best practices and expert insights.
