>The best experience by far is a yubikey nano since it is mostly permanently attached to your laptop.
Unfortunately ports are increasingly at a premium. You basically need to "mostly permanently" block the use of one of your USB ports for this to work. It's OK with my old MacBook Pro which has a USB port I mostly don't need to use for other purposes but thinner/lighter laptops don't have a lot of ports to spare.
