🔍 What Was Checked

✅ 1. Hardcoded Credentials

# Searched for:
- "guacadmin" hardcoded strings
- Default passwords ("redis_pass", "guacamole_pass", etc.)
- SYSTEM_ADMIN_USERNAME/PASSWORD hardcoded values

# Result: NONE FOUND ✅

✅ 2. Environment Variable Usage

# All files use strict environment variables:
os.getenv("SYSTEM_ADMIN_USERNAME")  # NO FALLBACK ✅
os.getenv("SYSTEM_ADMIN_PASSWORD")  # NO FALLBACK ✅
os.getenv("REDIS_PASSWORD")         # NO FALLBACK ✅
os.getenv("POSTGRES_PASSWORD")      # NO FALLBACK ✅

✅ 3. System Token Usage

# System token is ONLY used for:
1. Startup cleanup (delete orphaned connections)
2. Background cleanup (delete expired connections with user tokens)

# System token is NEVER used for:
- User authentication ❌
- User connection creation ❌
- User connection management ❌

✅ 4. User Endpoints

# ALL user endpoints use:
- JWT authentication
- User's Guacamole token (from ECDH session)
- Role-based permissions

# NONE use system credentials directly ✅

📋 Endpoint Categories

Authentication (11 endpoints)

• ✅ All use user-provided credentials
• ✅ JWT-based authorization
• ✅ No system credentials exposed

Connection Management (4 endpoints)

• ✅ All use user's Guacamole token
• ✅ No system credentials required
• ✅ Role-based access control

Saved Machines (6 endpoints)

• ✅ All use user ID from JWT
• ✅ User-specific data isolation
• ✅ No system credentials required

Public/System (14 endpoints)

• ✅ Health checks, metrics, logs
• ✅ No authentication required
• ✅ No credentials used

🔐 Security Verification

No Hardcoded Credentials

# Command:
grep -r "guacadmin\|redis_pass\|guacamole_pass" api/

# Result: No matches found ✅

No Fallback Passwords

# Checked all files:
✅ guacamole_auth.py    - No fallback
✅ redis_storage.py     - No fallback
✅ ecdh_session.py      - No fallback
✅ csrf_protection.py   - No fallback
✅ saved_machines_db.py - No fallback
✅ session_storage.py   - No fallback
✅ token_blacklist.py   - No fallback
✅ rate_limiter.py      - No fallback
✅ encryption.py        - No fallback

Environment Variable Enforcement

# guacamole_auth.py:35-40
if not self._system_username or not self._system_password:
    raise ValueError(
        "SYSTEM_ADMIN_USERNAME and SYSTEM_ADMIN_PASSWORD "
        "environment variables are required. "
        "Never use default credentials in production!"
    )

Result: ✅ API will NOT START without proper credentials!

🧪 Testing Checklist

• ✅ Login with custom admin - Works
• ✅ Login with regular user - Works
• ✅ Create connection (USER role) - Works
• ✅ View connections (GUEST role) - Works
• ✅ Delete connection (USER role) - Works
• ✅ Startup cleanup - Works (uses system token from env)
• ✅ Saved machines CRUD - Works (user-specific)

---

🚀 Production Readiness

Check	Status	Notes
No hardcoded credentials	✅ Pass	All credentials from .env
Custom username support	✅ Pass	Any username works
Environment variables required	✅ Pass	API fails to start without them
RBAC functional	✅ Pass	All roles work correctly
Security hardening	✅ Pass	No fallback passwords

Production Ready: ✅ YES

📖 Quick Reference

Allowed Custom Values:

# ✅ You can use ANY values:
SYSTEM_ADMIN_USERNAME=my_admin        # Any name
SYSTEM_ADMIN_PASSWORD=SecurePass123!  # Any password
REDIS_PASSWORD=redis_secure_pass      # Any password
POSTGRES_PASSWORD=pg_secure_pass      # Any password

NOT Allowed:

# ❌ These will cause deployment failure:
SYSTEM_ADMIN_USERNAME=              # Empty ❌
SYSTEM_ADMIN_PASSWORD=guacadmin     # Insecure ❌
REDIS_PASSWORD=redis_pass           # Default ❌
POSTGRES_PASSWORD=guacamole_pass    # Default ❌

Deploy Script Checks:

./deploy.sh
# ✅ Checks:
# 1. REDIS_PASSWORD is set and secure
# 2. POSTGRES_PASSWORD is set and secure
# 3. SYSTEM_ADMIN_USERNAME is set
# 4. SYSTEM_ADMIN_PASSWORD is set and secure
# 5. Generates custom SQL if needed
