Abstract: A technique for authenticating a user device with an application package server implementing an application. The device obtains a secondary identifier, allowing it to receive notifications relating to the application. Next, the device dispatches, while being identified by a main identifier associated with the device by way of a security module, a signalling message including the secondary identifier. Subsequent to this dispatching, the device receives a notification relating to the application which is addressed to it while being identified by the secondary identifier. This notification, the dispatching of which has been commanded by the application package server, includes the main identifier and an authenticator. The device then dispatches an authentication request to the application package server. This authentication request includes the main identifier and the authenticator that was received.
