Creación de un prototipo de sistema de one-time password (otp) para un sistema de autenticación de dos factores: implementación de un prototipo de sistema generador otp basado en hotp y envió por correo electrónico.

Abstract

This project proposes the creation of a prototype that uses one-time password (OTP) in a two-factor authentication system. A systematic study of the literature was carried out in order to know the different OTP protocols that exist, as well as their main advantages and disadvantages. With this previous study, the OTP protocol to be used was selected, as well as the different methods of delivering the OTP to the user. Next, the development phase began by first defining the requirements needed to meet the objectives of this work, then a high-level mockup was made and the necessary tools and frameworks were selected to complete the prototype (e.g. programming languages, database manager, agile methodologies for software development, among others). And finally, functional tests were performed in order to evaluate the performance of the developed prototype, detailing the criteria with which the tests were performed. It is worth specifying that the selection criteria used to carry out these evaluations focused mainly on discerning the delivery method preferred by the end users.
