Method for accessing a service provided on a mobile terminal (T2) by a server contributing to providing the service, referred to as application server (SP2), the method being implemented by the mobile terminal and comprising the following steps: • transmitting (G1) a request (TRq0) comprising an identifier of a subscriber to a subscription with a mobile operator (MNO), referred to as subscriber identifier (MNOSiD1), the subscriber identifier being based on information provided by a security module of the mobile terminal, and inserted into the request (TRq0) without the involvement of the user; the request being transmitted to a translation function (TR) of the mobile operator; • receiving (G4) a response (TRp0) from the translation function (TR) of the mobile operator comprising information relating to the subscriber identifier (MNOSiD1), referred to as identification code (tempAlias), and an address of a discovery server (@dmc); • transmitting (G5) a discovery request (DRq3) to the application server (SP2), comprising the address of the discovery server (@dmc); • receiving (G8) a response (DRp3) from the application server (SP2), comprising an address (@auth) of an authentication server (AUTH) of the mobile operator (MNO); • transmitting (G9) an authentication request (AuthRq) comprising the identification code (tempAlias), the authentication request (AuthRq) being transmitted to the authentication server (AUTH); • receiving (G12) an authentication response (AuthRp) comprising information relating to the identification code (tempAlias), referred to as authentication code (authCode) ; • transmitting (G13) a request to access the service (SRq) comprising the authentication code (authCode), the request (SRq) being transmitted to the application server (SP2) . • transmitting (G1) a request (TRq0) comprising an identifier of a subscriber to a subscription with a mobile operator (MNO), referred to as subscriber identifier (MNOSiD1), the subscriber identifier being based on information provided by a security module of the mobile terminal, and inserted into the request (TRq0) without the involvement of the user; the request being transmitted to a translation function (TR) of the mobile operator; • receiving (G4) a response (TRp0) from the translation function (TR) of the mobile operator comprising information relating to the subscriber identifier (MNOSiD1), referred to as identification code (tempAlias), and an address of a discovery server (@dmc); • transmitting (G5) a discovery request (DRq3) to the application server (SP2), comprising the address of the discovery server (@dmc); • receiving (G8) a response (DRp3) from the application server (SP2), comprising an address (@auth) of an authentication server (AUTH) of the mobile operator (MNO); • transmitting (G9) an authentication request (AuthRq) comprising the identification code (tempAlias), the authentication request (AuthRq) being transmitted to the authentication server (AUTH); • receiving (G12) an authentication response (AuthRp) comprising information relating to the identification code (tempAlias), referred to as authentication code (authCode) ; • transmitting (G13) a request to access the service (SRq) comprising the authentication code (authCode), the request (SRq) being transmitted to the application server (SP2) . <EOS>
