Why do I have only one Chrome listed in my devices even though I have multiple computers?
Chrome (and other browsers) are designed to protect your privacy as you browse the web. One of the ways they do this is working to prevent reliably identifying specific computers.
Because we can’t reliably tell computers apart as a browser extension, we treat each browser as one device. If you want to push between specific computers, I suggest you check out our desktop apps. You can get them from our Apps page.
