Abstract
Passy is an open-source Cybersecurity & Ethical Hacking project. Offline password manager with cross-platform synchronization. Passy is an offline password manager with cross-platfrom synchronization. It is built using Dart, Android, Flutter. Key capabilities include: Security – All your information is encrypted in AES and stored offline on your devices, providing highest-tier security; Synchronization – Share data between separate devices within seconds; 2FA codes - Keep your 2FA codes safe and sound in offline storage. The complete source code is publicly available on GitHub under the GNU General Public License v3.0, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.
1. Introduction
Passy is an offline password manager with cross-platfrom synchronization.
2. Objective
Offline password manager with cross-platform synchronization
This project demonstrates how Dart, Android, Flutter can be applied to a real-world Cybersecurity & Ethical Hacking problem.
3. Key Features / Modules
- Security – All your information is encrypted in AES and stored offline on your devices, providing highest-tier security.
- Synchronization – Share data between separate devices within seconds.
- 2FA codes - Keep your 2FA codes safe and sound in offline storage.
- Entry sharing – Send entries to your friends and family.
- Biometrics – Quickly unlock the app using your fingerprint.
- Multipurpose – Store passwords, payment cards, notes, id cards and identities, all in one place.
- Autofill – Quickly fill fields in apps and websites without having to open the app.
- Browser extension - Use autofill and add new entries on the fly right from your browser. (See https://github.com/GlitterWare/Passy-Browser-Extension)
- Passy Cloud - Support this free project and get secure, automatic online synchronization in return. (disabled by default - base app and manual QR-powered sync remain free forever)
