Organizations face challenges managing the growing number of customer identities across their digital properties, leading to security issues and poor user experience. To address these challenges, federated authentication and single sign-on (SSO) have emerged as effective solutions, offering enhanced security and user experience while reducing IT support costs. Federated authentication allows users to access services across multiple organizations with a single set of credentials, facilitated by trust relationships between different domains. In contrast, SSO enables access to various applications within a single organization, using one set of login credentials. While both approaches share the goal of simplifying user access, federation is more suited for cross-domain interactions, whereas SSO is ideal for streamlined access within a single entity. Descope, a no-code CIAM platform, offers solutions to implement both federation and SSO, helping organizations manage authentication and identity through user-friendly workflows.
