Status: Unmaintained — This project is no longer actively developed as of October 2024.
LibrePass Android is a cloud-based password manager built for Android with a focus on simplicity, security, and performance. The application provides users with a seamless way to generate, manage, and synchronize secure passwords across multiple devices.
This project was a hobby project that served as an incredible learning experience. It taught me valuable lessons about:
- Modern Android development with Kotlin and Jetpack Compose
- Cryptography and security implementation in mobile applications
- Cloud synchronization and backend integration patterns
- Clean architecture and modular project structure
- Multi-module Android projects with feature separation
- User authentication and biometric security
- Dependency injection with Dagger Hilt
While the project is no longer maintained, the codebase remains a testament to these learnings and serves as a reference implementation for many Android development practices.
- ✅ Advanced Password Encryption — All passwords stored in an encrypted vault
- ✅ Secure Password Generation — Generate strong, unique passwords with customizable parameters
- ✅ Biometric Unlock — Face and fingerprint authentication (Android 9+)
- ✅ Cross-Device Synchronization — Sync passwords securely across devices via cloud
- ✅ Material 3 Design — Native Android 12+ system theme support with dynamic colors
- ✅ QR Code Integration — Support for TOTP (Time-based One-Time Password) scanning
- ✅ Vault Auto-Lock — Automatically lock vault after configurable inactivity period
- ✅ Dark Mode — Full dark mode support with Material 3
- ✅ Offline Support — Works offline with local database synchronization
- ✅ Multi-Language Support — Translations contributed by the community
LibrePass Android was previously available on app stores but is no longer maintained:
- F-Droid — Previously available, removed due to project being unmaintained
- IzzyOnDroid — Previously available, removed due to project being unmaintained
- GitHub Releases — Historical releases still available for reference
This application implements several security measures:
- Encrypted Storage — All passwords encrypted using industry-standard algorithms
- Biometric Authentication — Secure unlock using fingerprint/face recognition
- Automatic Vault Lock — Vault locks automatically after period of inactivity
- HTTPS Communication — Secure cloud synchronization over encrypted channels
- No Password Logging — Passwords are never logged or persisted unencrypted
Note: This is a hobby project. For production use, consider security audits and professional password managers with established security track records.

This hobby project taught me invaluable lessons about:
- ✅ Modern Kotlin & Compose patterns for building responsive UIs
- ✅ Multi-module Android architecture with clean separation of concerns
- ✅ Jetpack components (Hilt, Navigation, Biometric, Lifecycle)
- ✅ User authentication flows and biometric integration
- ✅ Material Design 3 implementation and dynamic theming
- ✅ Building performant Android applications at scale
- ✅ Implementing end-to-end encryption in mobile applications
- ✅ Secure credential handling and storage practices
- ✅ Biometric authentication and secure unlock mechanisms
- ✅ HTTPS communication and secure data synchronization
- ✅ Password generation algorithms and best practices
- ✅ Security considerations in real-world applications
- ✅ Cloud synchronization patterns and offline-first architecture
- ✅ Dependency injection with Dagger Hilt at scale
- ✅ Community localization and internationalization
- ✅ Multi-module project structure and gradle organization
This project was a comprehensive learning experience that combined practical Android development with real-world security challenges. It provided insights into how modern password managers work and the complexity involved in securing user data.
Built with ❤️ as a learning experience in Android development
