What is SAML Assertion?
SAML Assertion can be defined as the package of information that supplies information regarding users, logins, attributes, and more made by SAML authority between the identity provider and service provider. When a user logs in through Single Sign-On (SSO) once through an identity provider, the identity provider passes the SAML attribute to the service provider (web or mobile application), provided the user attempts to access different services within that network.
