Passary is a zero-trust, offline-only password manager designed for users who want the highest level of privacy and complete control over their data. Unlike cloud-based password managers that rely on accounts, syncing, and remote servers, Passary keeps everything on your device. Your vault never leaves your computer, and no information is ever transmitted or stored externally. This creates a minimal attack surface and eliminates the risks associated with centralized data breaches, provider outages, and account takeovers.

At the core of Passary is a modern, transparent security model. All encryption happens locally with AES-256-GCM, and the master password is protected using Argon2id - two of the most trusted cryptographic standards available today. Your encrypted vault is stored directly on your filesystem using the File System Access API, giving you full ownership of the file and allowing you to manage backups in your own way.

Passary requires no registration, no cloud account, and no tracking. You simply create a vault, set your master password, and use the app entirely offline. The interface is streamlined and fast, built with React and Next.js to offer a clean workflow suitable for both technical and non-technical users.

Passary is built for privacy-conscious individuals, developers, security-focused users, and anyone who prefers a password manager that does not depend on third-party infrastructure. Whether you want a simpler security model, maximum isolation from online threats, or a tool that works anywhere without syncing, Passary offers a predictable and secure alternative to traditional cloud password managers.

Passary's answer

Passary is built around a strict offline-first, zero-trust philosophy.
