Identity providers (IdPs) have become crucial in modern authentication by facilitating centralized login methods, such as social login and single sign-on (SSO), which have gained popularity over the past decade. Users appreciate the convenience of using existing identities on platforms like Google to access other services, reducing the frustration of creating new accounts. IdPs manage digital identities by interacting with service providers (SPs) to streamline authentication, authorization, and account management processes, often using protocols like SAML and OpenID Connect (OIDC). This approach benefits both consumers and businesses by alleviating password fatigue and ensuring security and compliance. The integration of IdPs can be a complex decision for app developers, who must choose between in-house development or leveraging external services like Descope, which offers tools for adding authentication, authorization, and user management with ease.
