During the research, method for providing two-factor authentication in operating systems working with authentication services with centralized account databases in telecommunication networks

The work is dedicated to the development of a method for integrating two-factor authentication into operating systems by integrating the second factor into a centralized account database.

The work described scheme of an authentication process by using an additional component, the high-level scheme of interaction of system modules that implements the proposed method, sequence diagram of interaction of modules during user registration, authentication process using the proposed method.

Method is based on injecting OTP directly into the authentication service with a centralized account database.

The developed system consists of 9 interconnected modules, in which 7 relate directly to the system and 2 additional blocks (user and services).

In the proposed method, the authentication process has been improved by integrating the second factor into an authentication service with a centralized account database. This improvement made it possible to achieve universality, shorten the authentication time, and achieve the inexpediency of compromising the first factor.

The proposed method lacks an additional segment (service for checking the second factor).
