• Database credentials are now stored in environment variables (.env file)
• Database password has been updated to a secure value
• All services use environment variable references instead of hardcoded credentials

The following database credentials are configured in .env:

POSTGRES_DB=microservices_platform
POSTGRES_USER=app_user
POSTGRES_PASSWORD=Kl_P1_M1cr0serv1ces_2025_SecureDB!#

1. Environment Variables: All database credentials moved from hardcoded values to environment variables
2. Strong Password: Database password updated with complexity requirements
3. Documentation: Removed hardcoded credentials from all documentation files
4. Separation of Concerns: Configuration separated from code

⚠️ Critical: The .env file contains sensitive credentials and should NEVER be committed to version control.

✅ Protected: The .env file is already in .gitignore to prevent accidental commits.

When deploying to production, consider these additional security measures:

1. Secrets Management: Use a proper secrets management system (Docker Secrets, Kubernetes Secrets, HashiCorp Vault)
2. Database Access: Restrict database access to only required services
3. Network Security: Use private networks for database communication
4. Regular Updates: Rotate passwords regularly
5. Monitoring: Implement logging and monitoring for database access

If credentials are compromised:

1. Immediately change the password in .env
2. Restart all database-dependent services: docker compose restart database auth-service lol-tracking-service
3. Review access logs for suspicious activity
