<p>A system and method are disclosed for generating and communicating an Authentication Code in a network. An access request is sent from a user terminal (101A, 101B) to a first remote system (102), wherein the access request includes at least a network address of the user terminal (101B). The access request is received at a second remote system (103) and an USSD Access Code is generated using at least the network address, and sent to an USSD enabled user terminal (101B). The USSD enabled user terminal (101B) sends an USSD Service Request including the generated USSD Access. The USSD Access Code in the USSD Service Request is authenticated at the second remote system (103) and, in reply to a positive authentication, an Authentication Code is generated at, and sent to the USSD enabled terminal (101B) by, the second remote system (103). The USSD enabled terminal (101B) sends the USSD Authentication Code to the first remote system (102) and gains access thereto.</p> |
