SSO SSI

Wat is het verschil tussen Single Sign On en Single Sign In? Volgens Wikipedia is er geen verschil (meer).

Vergelijk Login en Logon dat tegenwoordig ook als synoniem wordt gebruikt.

Wat wel nog bestaat als aanpalend begrip is:

Enterprise SSO (ESSO): This is an alternative to "true SSO" approach. "Enterprise SSO" (ESSO) is using agents that are installed on every workstation. The agent watches when a login window is displayed and enters username and password before user notices anything. It is something like "remember password" feature in browsers but much faster. It does not require modification of the applications therefore the deployment is much cheaper when compared with true SSO.

single sign-off is the property whereby a single action of signing out terminates access to multiple software systems.
