I have original yubikeys, nanos, bluetooth, and usb-c keys. I currently keep them in a pencil case along with all my dongles, and I usually have to guess which one goes to what. Key labels? Sure, except I also tend to leave one in each laptop ... N organizations => N VPNs => N yubikeys, plus M personal accounts, plus not everything has transitioned from USB-A to USB-C, so in some cases I have more than one for an org. /sigh.Any suggestions? Google Shopping, Amazon, and Yubico are not terribly helpful here.
