Security Considerations

• Store sensitive configuration files with restricted permissions (600)
• Use app passwords for email authentication
• Consider encrypting configuration files containing passwords
• Run with minimal privileges
• Regularly update dependencies

Troubleshooting

Common Issues

1. WebDriver not found:

   # Install geckodriver for Firefox
   # On Ubuntu/Debian:
   sudo apt install firefox-geckodriver
   
   # On macOS:
   brew install geckodriver
   

2. Login failures:

   • Verify credentials in configuration
   • Check if Tello website structure has changed
   • Try running with --verbose for detailed logs

3. Email sending failures:

   • Verify SMTP settings
   • Use app passwords for Gmail
   • Test with tello-renewal email-test

4. Browser automation issues:

   • Try different browser types in configuration
   • Disable headless mode for debugging
   • Check browser and WebDriver versions

Debug Mode

Run with verbose logging to troubleshoot issues:

tello-renewal --verbose renew --dry-run

Log Files

Check log files for detailed error information:

tail -f tello_renewal.log
