🌍 Introduction

In today's digital world, users maintain dozens or even hundreds of online accounts. Managing these credentials manually is risky and inefficient. Many people reuse passwords or store them insecurely, making them vulnerable to cyber attacks.

The Secure Password Manager is designed to eliminate these risks by providing a centralized, encrypted vault where users can safely store and manage credentials.

This project applies real cybersecurity concepts including:

• Hashing
• Encryption
• Secure authentication
• Password strength evaluation
• Vault locking mechanisms
