TL;DR - 3 Commands to Deploy:

# 1. Clone repository
git clone https://github.com/emRival/PMJ-Secure.git && cd PMJ-Secure

# 2. Configure for your domain (replace with your actual domain)
cat > .env << 'EOF'
RP_ID=yourdomain.com
ORIGIN=https://secure.yourdomain.com
EOF

# 3. Run!
docker-compose up -d --build

That's it! App runs on port 3009.

Next Steps:

• Setup Nginx Proxy Manager → Point to your-server-ip:3009
• Enable SSL with Let's Encrypt
• Access https://secure.yourdomain.com
• Register account and start using!

For detailed guide, see Full Documentation below.

To update the application to the latest version on your server (LXC/Docker), follow these simple steps:

1. Pull the latest code

   git pull origin main

2. Rebuild and Restart Container

   docker-compose down
   docker-compose up -d --build

3. Verify Update Check the application logs to ensure everything started correctly:

   docker-compose logs -f

On the main dashboard, you can generate strong random passwords instantly.

• Customization: Adjust length (up to 64 chars) and include/exclude Uppercase, Lowercase, Numbers, and Symbols.
• One-Click Copy: Click the generated password card to copy it immediately. No verification needed for newly generated passwords.

Save your important credentials to your personal encrypted vault.

• Organization: specific titles and usernames for each entry.
• Privacy: Passwords are hidden (••••••) by default.
• Search: Real-time filtering to find credentials quickly.

To protect your most sensitive data, PMJ Secure implements a smart verification system.

• Trigger: When you try to View, Edit, or Copy a saved password from the vault, you will be asked to re-enter your login password.
• 10-Minute Session: Once verified, you enter a "Unlock Mode" for 10 minutes.
• Global Floating Timer: A floating timer (e.g., 🔓 9:45) appears at the bottom-right of your screen, letting you know how much time you have left.
• Persistence: You can refresh the page or navigate away, and your unlock session will remain active until the timer runs out.
• Auto-Lock: When the timer hits 0, or if you click Sign Out, the vault automatically locks again.

PMJ Secure provides true PDF encryption using server-side generation with PDFKit.

• How It Works:
  1. Click "Export PDF" and enter your login password
  2. Server generates a PDF with all your vault passwords
  3. PDF is encrypted using 128-bit RC4 encryption with your password
  4. Encrypted PDF is downloaded to your device
• Security: The exported PDF file cannot be opened without your exact password. Even if someone steals the file, they cannot view its contents.
• Permissions: The PDF is read-only with printing and copying allowed, but modification is disabled.
• Excel Import/Export: Easily migrate your data in bulk for batch password operations.

PMJ Secure supports modern passwordless authentication using Passkeys (WebAuthn standard).

Passkeys are cryptographic credentials stored securely on your device. They use biometric authentication (fingerprint, Face ID, Windows Hello) or device PIN for login - no passwords needed!

• ✅ Faster Login: Just scan your fingerprint - no typing
• ✅ More Secure: Phishing-resistant, no passwords to steal
• ✅ Privacy: Biometric data never leaves your device
• ✅ Multi-Device: Register multiple passkeys (iPhone, MacBook, etc.)

1. Login with your username and password
2. Go to Account Settings
3. Scroll to "Passkey / Biometric Login" section
4. Click "➕ Add Passkey / Biometric"
5. Name your passkey (e.g., "iPhone 13 Pro", "MacBook Air")
6. Scan your biometric when prompted
7. ✅ Passkey registered!

After registration, you can login without typing anything:

1. Go to Login Page
2. Click "🔑 Login with Passkey / Biometric" (don't enter username)
3. Browser shows your saved passkeys
4. Select your passkey
5. Scan biometric
6. ✅ Logged in instantly!

Optional: You can still enter username first if you have multiple accounts

• 📱 iPhone/iPad: Touch ID, Face ID
• 📱 Android: Fingerprint, Face Unlock
• 💻 Mac: Touch ID
• 💻 Windows: Windows Hello (fingerprint, face, PIN)
• 🔑 Hardware Keys: YubiKey, Titan Key, etc.

• ⚠️ HTTPS Required (except localhost for testing)
• ⚠️ Valid Domain (IP addresses not supported in production)

• View all registered passkeys in Account Settings
• Delete passkeys you no longer use
• Register multiple passkeys for different devices
• Each passkey shows creation date and last used timestamp

PMJ Secure is built with performance, security, and simplicity in mind. We chose a modern stack that delivers a lightning-fast user experience while maintaining robust security standards.

• SvelteKit: The meta-framework for Svelte. We use SvelteKit for its hybrid rendering capabilities (SSR + CSR), which provides:
  • Zero-compromise performance: Smaller bundle sizes compared to React/Vue.
  • Server-Side Rendering (SSR): For fast initial page loads and SEO.
  • API Routes: Integrated backend logic without needing a separate server.

• Node.js: The runtime environment for our server-side logic.
• SQLite (better-sqlite3): A high-performance, serverless SQL database.
  • Why SQLite? It allows the entire application to be self-contained in a single Docker container, making backups as simple as copying a file (passwords.db). No complex database setup required.

• bcryptjs: Industry-standard library for hashing user passwords. We never store plain-text passwords.
• @simplewebauthn/server & @simplewebauthn/browser: WebAuthn implementation for Passkey/biometric authentication.
• otplib & qrcode: Standards-compliant libraries for generating and verifying TOTP codes for 2FA.
• Session Management: Custom implementation using secure, HttpOnly, SameSite=Strict cookies to prevent XSS and CSRF attacks.
• Rate Limiting: Custom middleware to prevent brute-force attacks on registration and login endpoints.

• pdfkit: Server-side PDF generation with native encryption support (128-bit RC4).
• Security First: PDFs are generated and encrypted on the server to ensure proper password protection that cannot be bypassed.

We take security seriously. Here is how we protect your data:

1. 🔐 Passkey / Biometric Authentication (WebAuthn): Modern, phishing-resistant authentication using device biometrics. Credentials are discoverable (resident keys) allowing usernameless login.
2. Two-Factor Authentication (2FA): Adds a critical second layer of defense. Even if your password is stolen, an attacker cannot access your account without your physical device. We also support Emergency Password Reset via 2FA.
3. Sudo Mode: Sensitive actions (viewing, editing, or copying passwords) require you to re-enter your master password. This session stays active for 10 minutes, balancing security with convenience.
4. Military-Grade PDF Encryption: When you export your vault to PDF, the document is generated server-side and encrypted with 128-bit RC4 encryption using your master password. The PDF cannot be opened without the exact password, even if the file is intercepted or stolen.
5. Local-First Design: Your data lives on your server (or local machine), not in a third-party cloud. You own your data completely.

# Database Path
DB_PATH=/app/data/passwords.db
EOF

Important Notes:

• RP_ID: Your base domain (e.g., yourdomain.com or secure.yourdomain.com)
• ORIGIN: Full HTTPS URL users will access (e.g., https://secure.yourdomain.com)
• ⚠️ IP addresses are NOT supported for Passkey authentication
• ⚠️ HTTP is NOT recommended for production (except localhost testing)

The default docker-compose.yml is ready for production. Update if needed:
