A federated identity in information technology is the means of linking a person's electronic identity and attributes, stored across multiple distinct identity management systems.
Related to federated identity is single sign-on (SSO), in which a user's single authentication ticket, or token, is trusted across multiple IT systems or even organizations. SSO is a subset of federated identity management, as it relates only to authentication and is understood on the level of technical interoperability.

Famous quotes containing the words federated and/or identity:
“The Federated Republic of Europe—the United States of Europe—that is what must be. National autonomy no longer suffices. Economic evolution demands the abolition of national frontiers. If Europe is to remain split into national groups, then Imperialism will recommence its work. Only a Federated Republic of Europe can give peace to the world.”
—Leon Trotsky (1879–1940)
“One of the most highly valued functions of used parents these days is to be the villains of their children’s lives, the people the child blames for any shortcomings or disappointments. But if your identity comes from your parents’ failings, then you remain forever a member of the child generation, stuck and unable to move on to an adulthood in which you identify yourself in terms of what you do, not what has been done to you.”
—Frank Pittman (20th century)
