LocalPass: A Secure Offline Password Manager

  • Unique Paper ID: 196000

  • Abstract:
  • With the exponential rise in digital account ownership, safeguarding user credentials has emerged as a foremost concern in contemporary cybersecurity. Conventional cloud-hosted password management solutions, while convenient, carry inherent vulnerabilities stemming from centralized data repositories and their exposure to remote exploitation. This paper introduces LocalPass, an entirely offline credential management framework engineered to protect user authentication data without delegating control to any external party or networked service. Rather than transmitting sensitive information over the internet, LocalPass confines all data operations to the user's local environment, where credentials are secured within an AES-256 encrypted vault. The architecture incorporates a master password-based access mechanism, a cryptographically derived encryption key using PBKDF2, an automated password synthesis tool, and a portable encrypted backup subsystem. Empirical evaluation confirms that the fully local design substantially curtails the attack surface associated with centralized cloud storage, delivering a privacy-first credential management experience without sacrificing usability or functional depth.
