A data processing device including a microcontroller and configured to communicate with at least one remote system distributed on a network, said data processing device and said remote system adapted to store a plurality of parameters identifying a user account belonging to a subscriber, said data processing device comprising: a one-time parameter comprising the active account attached to said device designed for a one-time use, a permanent parameter identifying an account attached to said data processing device, said permanent parameter being deactivated,wherein said one-time and permanent parameter are stored in said at least one remote system, and said microcontroller is programmed to:c) using the one-time parameter to logon to the network when said data processing device is switched on;d) exchanging the one-time parameter with the permanent parameter, upon successful logon to the network, said permanent parameter becoming the permanent active account, wherein said first device and said at least one remote system store a parameter identifying a current active account attached to a second data processing device to replace, and upon successful logon to the network, a program automatically stored in said first device sends an activation request for exchanging the plurality of parameters from the old for the new one in said at least one remote system, with the current active account being deactivated. |
