Method of allowing establishment of a secure session between a device and a server

A server configured to establish a secure session with a first device by using a username and a password associated with a user, the first device comprising an interface configured to obtain the username entered by the user and to send the username to the server,

• wherein the server is configured to send a first login page to said first device and a second login page to a second device distinct from said first device, wherein the first login page is configured to allow the user providing the username for said first device without providing said password for said first device, wherein the second login page is configured to allow the user providing the password for said second device without providing said username for said second device, and wherein the server comprises a session means able to open a session, to send an identifier of the session to said first device and to associate the identifier with the username, wherein the server comprises a checking means adapted to receive an authenticating message from the second device, said authenticating message comprising a first reference data and an authenticating data, wherein the checking means is adapted to match up the username with the authenticating data if said first reference data matches the identifier and to check if the authenticating data has been correctly generated from the password, wherein the checking means is adapted to send a result message reflecting the result of the authenticating data checking in response to a polling message sent by the first device, and wherein said checking means is adapted to extract a second reference data from the polling message and to associate the result message with the polling message if said second reference data matches the identifier.
