Too bad the MacBook Pro (without TouchID) only has two USB-C ports.

I use one for charging and the other one for the external display.

Guess I'll have to buy the one with TouchID for extra security.

If you buy the one with TouchID, you can use the TouchID element for U2F as well: https://github.com/github/SoftU2F/pull/29

A USB-C hub would be cheaper.

Only if your looking for a USB-C to USB-A hub. There is a surprising lack of good USB-C multi-port hubs, let alone any that support USB PD on anything but the upstream port. You're just now starting to see any that even have generic pass-through of PD.

It is surprising; I understand the difficulty in making a USB-C multi-port hub, but it seems like a huge missed market opportunity. The MacBook is far from the only device with only a single USB-C port and a headphone jack.
