I used to keep a yubikey in a spare slot on my laptop. One day it fell out and subsequently escaped through an unnoticed hole in my backpack.

I've never lost a password because my backpack was overly abused.

That's why you keep it on your keychain and not in a spare slot on your laptop.

It's not possible to put a 5c nano on a keychain. They're intended to be kept in the slot at all times.
