What is SAML v2?

SAML v2 (Security Assertion Markup Language version 2) is an open standard for exchanging authentication and authorization data between security domains, meaning between an Identity Provider (IdP) and a Service Provider (SP). It enables Single Sign-On (SSO), allowing users to access multiple applications with a single set of credentials. It's commonly used in web-based authentication scenarios, cloud services, and enterprise identity management.
