Password Manager App

 

Password Manager App - BSc IT Project Guide

1. Introduction

The Password Manager App is a secure application that helps users store, generate, and manage their passwords in an encrypted format. It is designed to reduce password fatigue by allowing users to manage complex and unique passwords for various accounts.

2. Project Objectives

- To provide a secure environment for storing login credentials.
- To implement encryption techniques for data security.
- To generate strong, unique passwords.
- To offer cross-device synchronization (optional).
- To develop a simple and user-friendly interface.

3. System Modules

Key modules include:
a. User Authentication (PIN, Master Password, or Biometric)
b. Password Vault (Add, Edit, Delete credentials)
c. Password Generator
d. Search and Categorization
e. Data Encryption/Decryption
f. Backup and Restore (Local or Cloud)
g. Settings and Preferences

4. Technologies Used

- Frontend: Flutter / React Native / Kotlin / Swift
- Backend: Firebase (optional) / Node.js (for sync features)
- Database: SQLite (encrypted) / Room DB
- Libraries: AES Encryption, bcrypt, Biometrics API
- Tools: Android Studio, VS Code, Git

5. Development Methodology

Agile methodology is adopted to develop features iteratively. Security is a priority throughout development, with regular reviews of encryption and access control implementations.

6. System Design Overview

The app is designed with a local encrypted database and optional cloud sync. It requires a master key or biometric for unlocking the vault. Data is never stored in plain text, ensuring maximum security.

7. Testing

Testing includes:
- Security Testing: Ensure data encryption and safe access
- Functional Testing: Password generation, storage, and retrieval
- UI Testing: Layout and ease of use
- Compatibility Testing: Across different devices and OS versions

8. Conclusion

The Password Manager App addresses the growing need for secure password storage and generation. With encryption and usability at its core, the app helps users improve online security without sacrificing convenience.
