SAML

SAML (Security Assertion Markup Language) is an XML-based open standard for exchanging authentication and authorization data between identity providers and service providers. Ratified as an OASIS Standard in March 2005, SAML 2.0 enables single sign-on (SSO) across different applications and domains, reducing the need for users to manage multiple sets of credentials. It uses XML digital signatures and encryption to secure assertions exchanged between Identity Providers (IdP) and Service Providers (SP).
