# ========================================
# GENERATE SECURE JWT_SECRET
# ========================================

# Run this command to generate a secure random string:
node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"

# Copy the output and replace JWT_SECRET value

SUPER_ADMIN_EMAIL=admin@faceml.com
SUPER_ADMIN_PASSWORD=Admin@123


# ========================================
# SECURITY NOTES
# ========================================

1. NEVER commit .env file to git
2. Change JWT_SECRET to output from crypto command above
3. Change SUPER_ADMIN_PASSWORD after first login
4. Use strong database password
5. For production, consider using environment variables instead of .env file


# ========================================
# VERIFY .env FILE IS WORKING
# ========================================

# Start server and check if it connects to database
node server.js

# You should see:
# ✓ Database connected successfully
# 🚀 FaceML Backend API Server
# Server running on: http://localhost:3000
