"""
De'Longhi Device Info Retriever

This script logs into your De'Longhi account, retrieves an authentication token,
and then fetches information about your registered coffee machines or other
De'Longhi comfort devices.

It's designed as a simple, command-line tool that leaves no trace on your system,
as it cleans up the temporary token file it creates.

---
Installation:
You need to install two Python libraries. You can do this using pip:

pip install requests cremalink

---
How to run:
Save this file (e.g., as `delonghi_device_info.py`) and run it from your terminal:

python delonghi_device_info.py

The script will then prompt you for your De'Longhi account email and password.
