SAML enables Single-Sign On (SSO), a term that means users can log in once, and those same credentials can be reused to log into other service providers.

How SAML works for SSO?

SAML SSO works by transferring the user's identity from one place (the identity provider) to another (the service provider). ... The application identifies the user's origin (by application subdomain, user IP address, or similar) and redirects the user back to the identity provider, asking for authentication.

Is SAML SSO secure?

SAML SSO is easy to use and more secure from a user perspective as they only need to remember one set of user credentials. It also provides fast and seamless access to a site as every application they access does not prompt them to enter a username and password.
