The Security Assertion Markup Language, aka SAML, is a widely used open standard that allows authorization credentials to be transferred to service providers (SP) by identity providers (IdP). In essence, SAML implementation enables Single Sign-On, which means to log into several different websites; you can use one set of credentials. Managing one username per user is much easier than managing separate email logins, customer relationship management (CRM) applications, Active Directory, etc.
