What I am doing, and I find it to work really well is to have a yubikey nano (https://www.yubico.com/product/yubikey-5-nano) in one of the front USB ports of my PC case. Super easy to reach and takes no room at all.

Awesome project.

I have the USB-C version mounted under my desk with a USB-C extension cable. Works well.

I don't want to pay $50 for another Yubikey when I have a box full of $4 ESP32s, though.
