Quick Summary: 📝
Zero Password Manager is an open-source, self-hosted password manager built with Flutter, prioritizing privacy and security. It allows users to store passwords and crypto seed phrases securely on their own servers, employing end-to-end encryption and zero-knowledge principles.
Key Takeaways: 💡
✅ You self-host your password vault, ensuring complete physical control over your data.
✅ True zero-knowledge security: client-side AES-256-GCM encryption means your key never leaves your device and the server is cryptographically blind.
✅ Eliminates cloud subscriptions, vendor lock-in, and reliance on third-party trust.
✅ Includes robust security features like mandatory TOTP 2FA, biometric unlock, and WebAuthn/FIDO2 passkey support.
✅ Offers a seamless cross-platform experience (Android, iOS, Web, Desktop) powered by Flutter and FastAPI.

This project tackles a fundamental flaw in many popular password managers: the reliance on third-party servers to store your encrypted vault. While they often claim 'zero-knowledge,' the fact remains that your sensitive data, albeit encrypted, resides on someone else's hardware. Zero Password Manager offers a radical alternative by putting you in complete control. Your encrypted vault lives on a server you run, whether it's a home server, a personal VPS, or even a Raspberry Pi. This means you physically control the hardware that holds your secrets, eliminating the need to trust any external cloud provider with your data's physical location. The core of its security lies in robust client-side encryption. Your data is encrypted on your device before it ever gets sent to your self-hosted server, and crucially, your encryption key never leaves your device. This design ensures that your server is 'cryptographically blind' to your vault's contents; it simply stores encrypted data it cannot decipher. This approach provides true zero-knowledge security, where cryptographic proof, not just a company's promise, guarantees your privacy. For developers and privacy-conscious users, this offers significant advantages. It eliminates vendor lock-in and the need for cloud subscriptions, giving you complete autonomy over your password management solution. The project incorporates advanced security features like AES-256-GCM end-to-end encryption, PBKDF2-SHA256 for strong key derivation, and mandatory TOTP 2FA, providing an ironclad defense against unauthorized access. Further protections include blind site hashing, ensuring URLs are never stored in plaintext, and per-operation OTP gating for sensitive actions, along with replay attack protection. Modern conveniences haven't been overlooked, with support for biometric unlock (fingerprint and Face ID) and WebAuthn/FIDO2 passkeys, all integrated within a system where you retain ultimate ownership. Built with Flutter for a seamless cross-platform experience (Android, iOS, Web, Desktop) and a FastAPI backend, it's an excellent open-source project to explore, adapt, and contribute to, empowering you to manage your digital identity with unparalleled control and peace of mind.
