Many more services implement TOTP and not U2F, so this would tend to be seen as a useful thing for end users even if the technology is unattractive.

Actually, I just thought of a way you could make this work with a terminal command instead of a driver. You'd have to type something like:

date > /dev/cu.usbmodem*

and the OTP would appear on the HSM display. Would that work for you?

Yeah, I guess that could work since I usually don't log in to my business accounts from anywhere else but my own computer, so even if it needs a bit of configuration it's not that bad.

Just an idea, is there any USB device class that could be used to get the date and time? such that if you configure the SC4 to work with TOTP, when you plug it in a USB driver is installed that allows it to query the date and time?

Not that I know of. But it's a good idea if it turns out that such a class does exist. If you find one please let me know!
