Authy synchronizes across devices and works on a computer. If you're using Github then you at least have a computer. And using 2FA on your own computer at least guarantees that the access is from your computer. Sure, someone could hack your computer and get access to your GitHub, but if they're already on your computer, they can just change the code and do a git push too.
