Abstract: An arrangement for authenticating a user at a service provider is described. The arrangement makes use of the fact that a user of a mobile communication device can be readily and securely identified by a telecommunications provider and re-uses that authentication to identify the same user when accessing the service provider from a different client. The client instructs the mobile communication device to contact an identity provider at the telecommunications provider and shared secrets are exchanged between the identity provider, mobile communication device and client to confirm that the same user is at the client and the mobile communication device.
