Abstract: Embodiments provide methods, devices and computer program arranged to facilitate authenticated communication between a user device and a service associated with a network. One embodiment comprises an apparatus which, in response to authenticating a user device on the basis of a first authentication protocol, transmits a request for a credential of a first type to an authentication server associated with the network via a communications link therebetween, the credential of the first type being for use by the apparatus to obtain a credential of a second type on behalf of the user device from the authentication server. Subsequently, the apparatus transmits a request for a credential of a second type to the authentication server via the communications link therebetween, the credential of the second type being for use by the user device in establishing authenticated communication with the service. The credential of the second type is then transmitted to the user device.
