SAML or Security Assertion Mark-up Language is an open standard that allows identity providers (IdP) to pass authorization credentials to service providers (SP). SAML transactions use XML or Extensible Markup Language for standardized communications between the service providers and identity provider. SAML 2.0 enables Single-Sign On (SSO). With SSO, users can log in once to an application/platform by using their login ID and password and those same login credentials can be reused to log into other service providers.
