SecurityDriven Password Management Solution To Prevent Unauthorized Access And Credential Compromise

In the current developing digital technology, passwords serve as the primary line of defence protecting sensitive files, user accounts, and critical data. By the weak password practices, reuse of credentials across platforms, and inadequate storage mechanisms continue to expose individuals and organizations to a wide spectrum of cyber threats including credential stuffing, brute-force attacks, and data breaches. This paper presents the design and implementation of a Password Management Suite, a desktop application developed using Python and Tkinter that integrates multiple cryptographic and security-oriented features into a unified, user-friendly interface. The suite comprises four core modules: a cryptographically secure Password Generator, a real-time Password Strength Checker powered by the zxcvbn estimation engine, an AES-256-GCM encrypted ZIP Password Cracker for authorized recovery scenarios, and a file-level Folder Locker using AES-256-GCM encryption. A master password authentication mechanism secured via bcrypt hashing gates access to the entire application. Password generation history is persisted using Fernet symmetric encryption derived from a SHA256 key. The application demonstrates how the layered approach of cryptographic principles can be made accessible to non-expert users through thoughtful interface design.
