@th I got so sick of having to plug my Yubikey Neo 5 into my Thinkpad a zillion times a day that I bought a Yubikey Nano 5. I quickly grew sick of accidentally triggering it a zillion times a day. Having it spew into text boxes is bad, but it is awful when you have something like Lightroom open, which uses single key shortcuts. I'm back to using the Neo 5. I like the concept of the Nano, but they really need activation to be via a highly deliberate physical act.
