To authenticate a user possessing a first communication terminal (TC1) and a second communication terminal (TC2), the first terminal being connected to an application server (SApp) in order to access a service, this application server being connected to an authentication server (SAuth) capable of communicating with the second terminal, the authentication server (SAuth) receives a user identifier (IdU) transmitted from the first terminal and identifies the second terminal based on the received identifier. The server generates coding data (DonC) and transmits it to one of the two terminals, and transmits a command to the other one of the two terminals to invite the user to provide a set of data (EnsD) using the coding data received by said one of the two terminals. The server compares the set of data with secret data (DonS) using the coding data, in order to allow the user access to the application server (SApp). |
