Abstract:
1. A computer-implemented method of authenticating a user for usage of a portal at a user terminal, the method comprising steps of: obtaining at least one credential inputted by the user through the portal, the portal being accessed by the user via the user terminal; validating the user based on the obtained at least one credential; displaying, a code at the portal accessed by the user via the user terminal, wherein the code is generated by a server of the portal; transmitting, by the server, one or more user details and the generated code to an authentication module, wherein the authentication module is maintained as a separate entity that is independent of the server of the portal; initiating establishment, by the authentication module in communication with the server, of an audio session with the user at a registered device of the user, wherein the registered device is different from the user terminal; checking, by the authentication module, the establishment of the audio session at the registered device and invalidating the authentication of the user on failing to establish the audio session; receiving, by the authentication module, the code from the user through the registered device if the audio session is established with the user; comparing, by the authentication module, the code received from the user via the registered device during the established audio session with the generated code received from the server of the portal; and authenticating the user for usage of the portal at the user terminal based on the comparison.
