CONSOLIDATED AUTHENTICATION

A method and system for authenticating a user at a first computer to first and second applications installed in a second computer. The second computer receives from the user a first request to access the first application, and in response, the second computer redirects the first request to a third computer, and in response, the third computer determines that the user was previously authenticated and so notifies the second computer, and in response, the second computer returns a first session key to the third computer. The first session key enables a session with the first application but not with the second application. The second computer receives from the user a second request with a second session key to access the first and/or second application, and in response the second computer determines that the user is authentic and notifying the first and/or second application that the user is authentic.
