A method of authenticating a client to two or more servers coupled together via a communications network, wherein the client and a first server possess a shared secret. The method comprises authenticating the client to a first server using said shared secret, signalling associated with this authentication process being sent between the client and said first server via a second server, generating a session key at the client and at the first server, and providing the session key to said second server, and using the session key to authenticate the client to the second server.
