What is Single Sign-On (SSO)?
a) A mechanism of digitally “signing” the information exchanged between applications/systems.
b) A mechanism that enables a user to sign-in/login/authenticate to an application/system with his credentials only once and then seamlessly access other applications/systems available in the same domain of trust (e.g. Intranet portal of an organization) without the need to e-login with the credentials again.
c) A mechanism which enables using single physical “signature” to do all banking transactions!
d) None of the above.
