Abstract

App is an open-source Cybersecurity & Ethical Hacking project. 📱 Two-Factor Authentication (2FA) client for Android + Wear OS. A free open-source two factor authentication app for Android. It features encrypted backups, icons, categories and a high level of customisation. It is built using C#, Android. The complete source code is publicly available on GitHub under the GNU General Public License v3.0, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.

1. Introduction

A free open-source two factor authentication app for Android. It features encrypted backups, icons, categories and a high level of customisation. It also has a Wear OS companion app.

It supports TOTP (Time Based) and HOTP (Counter Based) authenticators using either SHA1, SHA256 or SHA512 hashing algorithms. Mobile-Otp (mOTP), Steam and Yandex are also supported.

2. Objective

📱 Two-Factor Authentication (2FA) client for Android + Wear OS

This project demonstrates how C#, Android can be applied to a real-world Cybersecurity & Ethical Hacking problem.
