Could Authy be of use for you perhaps? It seems like they have a desktop app, although I have no personal experience with it. Alternatively, GitHub supports the use of Security Keys which are physical devices that you can purchase for 2FA purposes, Yubico works great in my experience but there are other manufacturers, or even DIY solutions.
