- After the first build, you can change the admin password through the user management interface
- Additional users can be created through the registration page
+- Credentials are logged **only once** on first startup
+- Save the credentials immediately - they won't be shown again
+- Alternatively, set `ADMIN_PASSWORD` in `docker-compose.yml` to use a custom password

-1. Change the default admin credentials in your `.env` file
-2. ✅ Password hashing is implemented using bcrypt
-3. Use a strong `AUTH_SECRET` in environment variables (generate with `openssl rand -hex 32`)
-4. Enable HTTPS
-5. Consider implementing rate limiting
-6. Add CSRF protection
+## Security Features

-**Note**: Passwords are now securely hashed using bcrypt with 10 salt rounds before being stored in the database.
+This application implements enterprise-grade security following OWASP best practices:
+
+### ✅ Implemented Security Features
+
+1. **Auto-Generated Secrets**
+   - `AUTH_SECRET` automatically generated using cryptographic randomness
+   - Admin password auto-generated with 16 characters (uppercase, lowercase, numbers, symbols)
+   - All secrets stored securely in database
+
+2. **Password Security**
+   - Bcrypt hashing with 10 salt rounds
+   - Strong password requirements (8+ chars, uppercase, lowercase, number/symbol)
+   - Secure password reset with 8-character alphanumeric codes (1.8 trillion combinations)
+   - Session invalidation on password changes
+
+3. **CSRF Protection**
+   - Double-submit cookie pattern implementation
+   - Automatic token injection on all API requests
+   - Three-way validation (cookie, header, session database)
+   - Zero configuration needed in components
+
+4. **Session Management**
+   - Secure session tokens with HTTP-only cookies
+   - Automatic session expiration (24 hours)
+   - Session invalidation on security events (password changes, admin resets)
+   - Protection against session fixation attacks
+
+5. **Account Lockout (Dual-Layer Brute Force Protection)**
+   - IP-based rate limiting (existing)
+   - Per-account lockout: 10 failed attempts = 30 minute lock
+   - Automatic unlock after expiration
+   - Admin manual unlock capability via UI
+
+6. **User Management**
+   - Role-based access control (admin/user)
+   - Admin dashboard for user management
+   - Account lock status visibility
+   - Password reset functionality
+
+### 🔒 Production Recommendations
+
+1. ✅ Strong passwords - Enforced by application
+2. ✅ Password hashing - Bcrypt with salt rounds
+3. ✅ CSRF protection - Implemented
+4. ✅ Session security - HTTP-only cookies with expiration
+5. ✅ Account lockout - Dual-layer protection
+6. ✅ Secrets management - Auto-generated and stored securely
+7. **Enable HTTPS** - Configure reverse proxy (nginx/Caddy)
+8. **Regular backups** - Backup `/app/data` directory
+9. **Email security** - Use app-specific passwords for SMTP
+10. **Monitor logs** - Review failed login attempts
+
+### 🛡️ Security Compliance
+
+- **OWASP Top 10 2021**: Addressed broken authentication, injection, security misconfiguration
+- **Password Storage**: NIST-compliant bcrypt hashing
+- **CSRF Protection**: Industry-standard double-submit pattern
+- **Session Security**: Secure cookie attributes and expiration
+- **Brute Force Protection**: Account lockout + rate limiting
