What is the primary purpose of SAML Web Single Sign On?

The primary purpose of SAML (Security Assertion Markup Language) Web Single Sign-On (SSO) is to securely exchange authentication and authorization data between an identity provider and a service provider. This mechanism allows users to authenticate once and access multiple applications without needing to log in separately to each one.

SAML achieves this by using standardized XML-based assertions that communicate user identity and permissions, ensuring that the information is both secure and efficient. By facilitating a single point of authentication, SAML improves the user experience while maintaining security by reducing the need for multiple credentials.

In this context, the other choices do not align with the primary function of SAML SSO. Storing authentication logs, creating user accounts, and enhancing database security are not the main objectives of SAML, as they pertain to different aspects of security and user management rather than the core capability of SAML in facilitating secure and seamless access to resources.
