Core Principles

Zero-Storage Security
Decentralized Architecture
Deterministic Regeneration
Metadata Only

Local Processing
On-Demand Discovery
No Cloud Dependency
No Trust Required

Decentralized by Design: Unlike traditional password managers that store encrypted vaults on central servers, Smart Password Manager stores nothing. Your secrets never leave your device. Passwords are regenerated on-demand — no cloud, no database, no trust required.

Decentralized & Serverless — no central database, no cloud lock-in
No Password Database — eliminates password storage completely
Dark Theme Interface — easy on the eyes
Public Key Verification — verify secret knowledge without exposure
Edit Functionality — update descriptions and lengths anytime
Copy to Clipboard — quick password copying
Export/Import — backup and restore functionality
QR Code Export — transfer metadata to Android app
Linux Desktop Integration — create application shortcuts

Proof of Knowledge — public keys verify secrets without exposing them
Decentralized Trust — no third party needed
Deterministic Security — same secret + length = same password
Metadata Separation — non-sensitive data stored separately
Local Processing — no data leaves your computer
No Recovery Backdoors — lost secret = permanently lost access (by design)

Validation Rules: Secret phrase: minimum 12 characters · Password length: 12-100 characters

Create Smart Passwords — generate deterministic passwords from secret phrases
