Cybersecurity & Ethical HackingC#MIT

Abstract

Two Factor Auth Net is an open-source Cybersecurity & Ethical Hacking project. .Net library for Two Factor Authentication (TFA / 2FA). .Net library, available as NuGet package, for two-factor (or multi-factor) authentication using TOTP and QR-codes. This is a .Net port of the PHP TwoFactorAuth library (staying as close as possible to the PHP implementation, but using .Net conventions and codestyles). It is built using C#. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.

1. Introduction

.Net library, available as NuGet package, for two-factor (or multi-factor) authentication using TOTP and QR-codes. This is a .Net port of the PHP TwoFactorAuth library (staying as close as possible to the PHP implementation, but using .Net conventions and codestyles).

2. Objective
