Definition
Single sign-on (SSO) refers to a system by which a user only has to sign-in once to access multiple applications. The idea is to provide users with a minimum of digital identities since password fatigue has become a real issue in education. Often (and rightly so) learners are encourage to use a large variety of locally installed platforms and Internet services.
Local single sign-on (SSO) can be distinguished from Web single sign-on.
“Single sign-on (SSO) is a method of access control that enables a user to log in once and gain access to the resources of multiple software systems without being prompted to log in again. Single sign-off is the reverse process whereby a single action of signing out terminates access to multiple software systems.” (Wikipedia, retrieved 11:54, 22 August 2008 (UTC))
