I have a url that contains a token that is sensitive since it gives access to my home automation system that can unlock my doors, etc. If I turn on Valet Mode, it restricts access to Favorites, but not from opening the browser and clicking Back to land on the url I am trying to hide. Is there a way to clear your browser history without erasing all personal data? Lastly, when bringing in the car for service, Can you put it in Valet mode? Or does Tesla SC's require additional access?
