Over the past months, I’ve been building something I personally needed — a secure, self-hosted password manager where you fully own your data.
No SaaS. No hidden sync. No “trust us with your secrets”.
Just you, your keys, and full control.
🔐 What is this project?
This is a zero-knowledge password manager designed for people who:
don’t want to trust third-party services
prefer self-hosted solutions
care about privacy, encryption, and control
Everything is built around a simple idea:
Your data should never leave your control — encrypted end-to-end.
⚙️ Key Features
🔒 True End-to-End Encryption
All sensitive data is encrypted on the client
Server never sees your plaintext data
Zero-knowledge architecture
🏠 Fully Self-Hosted
Deploy it wherever you want
No dependency on external SaaS
Works in your own infrastructure
🔑 Multiple Unlock Methods
Flexible security model:
TOTP (2FA)
Biometrics
PIN code
👉 You can choose what fits your threat model
🎨 Clean UX/UI (3 Themes Included)
A lot of effort went into making it not just secure — but actually enjoyable to use:
3 built-in themes
smooth and minimal UI
designed for real daily usage
🌈 Upcoming: Theme Generator
One of the next big features:
custom theme generator
full UI personalization
making the app feel truly yours
📂 Advanced Structure
modular architecture
hidden/internal modules (TOTP, auth flows, etc.)
built with scalability in mind
📜 License
fully open source
non-commercial license
🤔 Why I built this
I was tired of:
trusting SaaS with sensitive data
closed-source password managers
limited control over security
So I decided to build something:
transparent, private, and fully under user control
🚧 Current Status
Core functionality is implemented
Encryption + auth flows are working
UX/UI is already polished
Project is actively evolving
🤝 Looking for Contributors
I’ve done a lot solo, but at this point:
this project needs more hands
I’m looking for people who are interested in:
security / cryptography
frontend (UX/UI improvements)
mobile / cross-platform
architecture & performance
open-source collaboration
💡 How You Can Help
Even small contributions matter:

sharing feedback
🔥 Why Join?
work on a real-world security product
contribute to privacy-first software
shape an open-source tool from early stage
build something meaningful (not just another CRUD app)
📌 Final Thoughts
This is still an early-stage project — which means:
you can directly influence what it becomes

zero_password_manager
Open-source self-hosted password manager built with Flutter. Store passwords and crypto seed phrases securely without cloud storage.
🔐 Zero Password Manager
Zero Cloud. Zero Tracking. Zero Compromise.
A privacy-first, self-hosted password manager built on true zero-knowledge principles.
Your vault lives on your server. Your key never leaves your device. Your secrets stay yours.
The Problem with Every Other Password Manager
Every major password manager — LastPass, 1Password, Bitwarden Cloud — ultimately stores your vault on someone else's server. "Zero-knowledge" in their marketing means they claim not to read your data. It doesn't mean they can't.
Zero Password Manager takes a different position: the server that holds your vault is one you run yourself. On your home server, your VPS, your Raspberry Pi. The encrypted vault sits on hardware you physically control.
Combined with client-side encryption that ensures the server is cryptographically blind to all vault contents, this is privacy that doesn't require trusting anyone.
No cloud subscription. No vendor lock-in. No breach notifications from a…

🔍 Security & Transparency Note
At this stage, the project has not been certified or audited by a third-party security company.
The main reason is simple:
- professional security audits are extremely expensive
- and the project is still at an early stage of development
However, there are a few important things to highlight:
- the project is fully open source
- the architecture is designed around zero-knowledge and end-to-end encryption principles
- everything is transparent and open for review
🚫 No Commercial Intent
This project is not built for commercial purposes.
There are no plans to turn it into a paid product — the goal is to build something:
- useful
- private
- and community-driven
🤝 Support Matters
Since this is an independent project, any kind of support really makes a difference:
- ⭐ starring the repository
- sharing the project
- giving feedback
- contributing code
Even something as simple as a GitHub star is a huge motivation to keep building and improving this project further.
Thank you — it genuinely helps more than you might think 🙌
