Single sign-on (SSO) has evolved from a desirable feature to a fundamental expectation for enterprise systems, significantly benefiting both developers and businesses by reducing risk, cutting costs, and enhancing user engagement. The SSO market is projected to grow substantially, reflecting its importance in unifying authentication across apps and services. Key advantages of SSO include enhanced security through reduced password risks and centralized authentication, streamlined customer access management, easier compliance with regulatory frameworks, and tangible cost savings by minimizing password resets and optimizing resource usage. SSO also improves user experience by reducing the need for multiple logins and enhances productivity for developers and IT staff by simplifying authentication processes. Furthermore, SSO enables secure identity federation across organizational boundaries, facilitating seamless interactions with external partners and customers. Organizations are encouraged to implement best practices such as using modern protocols, pairing SSO with adaptive multi-factor authentication (MFA), and continuously monitoring and auditing login activities to maximize the impact of SSO on security, compliance, and user experience. Descope offers a simplified, no-code approach to SSO implementation, allowing businesses to integrate SAML or OIDC SSO quickly, ensuring flexibility and ease of use.
