Terminal-based smart password manager with deterministic password generation. Generate, manage, and retrieve passwords without storing them - all from your command line. Your secret phrase never leaves your device.
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.

Summary: Software provided "AS IS" without warranty. You assume all risks.
Full legal disclaimer: See DISCLAIMER.md
- Zero-Storage Security: No passwords or secret phrases are ever stored or transmitted
- Decentralized Architecture: No central servers, no cloud dependency, no third-party trust required
- Deterministic Regeneration: Passwords are recreated identically from your secret phrase
- Metadata Only: Store only descriptions and verification keys
- Client-Side Generation: All cryptographic operations happen on your device
- On-Demand Discovery: Passwords exist only when you generate them
- Decentralized & Serverless: No central database, no cloud lock-in, complete user sovereignty
- Smart Password Generation: Deterministic from secret phrase
- Public/Private Key System: 30 iterations for private key, 60 for public key
- Secret Verification: Verify secret without exposing it
- Interactive Mode: Menu-driven interface for easy use
- Command-Line Mode: Scriptable operations for automation
- Export/Import: Backup and restore your password metadata
- Cross-Platform: Windows, Linux support
- Hidden Input: Secret phrase entry with asterisks masking
- Proof of Knowledge: Public keys verify secrets without exposing them
- Decentralized Trust: No third party needed — you control your secrets completely
- Deterministic Security: Same secret + length = same password, always
- Metadata Separation: Non-sensitive data stored in JSON file
- Local Processing: Secret and password never leave your device
- No Recovery Backdoors: Lost secret = permanently lost access (by design)
- Pointer-Based Security Paradigm - Architectural Shift from Data Protection to Data Non-Existence
- Local Data Regeneration Paradigm - Ontological Shift from Data Transmission to Synchronous State Discovery
Powered by smartpasslib-csharp — C# implementation of deterministic password generation.
Key derivation (same as Python/JS/Kotlin/Go/C# versions):
| Key Type | Iterations | Purpose |
|---|---|---|
| Private Key | 30 | Password generation (never stored, never transmitted) |
| Public Key | 60 | Verification (stored locally) |
Character Set: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$&*-_
Decentralized Architecture:
- No central authority required
- Metadata can be synced via any channel
- Your security depends only on your secret phrase
- Works offline — no internet connection required

- Minimum 12 characters (enforced)
- Case-sensitive
- Use mix of: uppercase, lowercase, numbers, symbols, emoji, or Cyrillic
- Never store digitally
- NEVER use your password description as secret phrase
✅ "MyStrongSecretPhrase2026!" — mixed case + numbers + symbols
✅ "P@ssw0rd!LongSecret" — special chars + numbers + length
✅ "КотБегемот2026НаДиете" — Cyrillic + numbers
❌ "GitHub Account" — using description as secret (weak!)
❌ "password" — dictionary word, too short
❌ "1234567890" — only digits, too short
❌ "qwerty123" — keyboard pattern
❌ Same as description — never use the same value as password description
There is no "forgot password" button. This is by design:
- No central server can reset your passwords
- No support team can recover your access
- Your secret phrase is the ONLY key
This is the price of true decentralization — you are completely in control.
