  > my point is you could also have any ultra-cheap device plugged into your computer that can run general-purpose crypto software and talk via USB, But you would need this ultra-cheap device plugged into your computer to be resistant to your computer being compromised. Do you know such an off-the-shelf device? > or your phone Well your phone has a very large attack surface as compared to a Yubikey. > You wouldn't have to pay > 50$ for a Yubikey. Are you sure about that? I have a Nitrokey 3C NFC that cost more than my Yubikey, and the Nitrokey can be flashed from my computer. Meaning that if my computer is compromised, then my Nitrokey is compromised. It's not clear to me that 50$ is expensive for a product that is not used by half the world and doesn't collect the private data of its users. I understand the frustration with the security issue, but I find it unfair to say "I would do better for < 1$".
