iCloud web session closes after few days even when I check the trust this device button

I want to access iCloud from my home PC without the 2 factor method. If my phone gets stolen I won't be able to track it because it will ask for the code that is in my phone. Is this possible?

I always check the "trust this device button" when I access iCloud web but after a few days it asks for the 2 factor code again.
