'''Federated Identity''' has two meanings really. |

'''Federated Identity''' is a property of [[authentication]] systems whereby [[credential|credentials]] of [[principal|principals]] are stored in a [[decentralized]] manner. |
|||
* On the one hand it is the virtual reunion of a person's user information (or [[principal]]), stored across multiple [[identity management]] systems. This information is [[Join (SQL)|joined]] together by use of a user's name. |
|||
* On the other hand it relates to a user's [[authentication]] across multiple IT systems or even organisations. |
|||
For example, a traveler could be a flight passenger as well as a hotel guest. If the airline and the hotel use a federated identity management system, they mutually trust eachother's [[authentication]] of the user. In effect, the traveler could identify as a customer for booking the flight and this identity can be used for the reservation of a hotel room. |

Federated Identity has two meanings really.
- On the one hand it is the virtual reunion of a person's user information (or principal), stored across multiple identity management systems. This information is joined together by use of a user's name.
- On the other hand it relates to a user's authentication across multiple IT systems or even organisations.
For example, a traveler could be a flight passenger as well as a hotel guest. If the airline and the hotel use a federated identity management system, they mutually trust eachother's authentication of the user. In effect, the traveler could identify as a customer for booking the flight and this identity can be used for the reservation of a hotel room.
