SAML facilitates secure web-based single sign-on (SSO) by allowing users to authenticate once and gain access to multiple services without needing to log in again. It uses XML-based assertions to pass user identity information between the identity provider (IdP) and service provider (SP).
Implementing SAML can significantly enhance user experience and security by reducing password fatigue and minimizing the risk of phishing attacks. Organizations adopting SAML should ensure proper configurations and maintain updated metadata to prevent vulnerabilities.
