Yubikey hardware token

Disabling Keyboard emulation on touch

By default the Yubikey has a Yubikey OTP mode enabled that does keyboard emulation on touch were it fills in a 44 char random string whenever you touch the yubikey for ~1.5seconds.

(Typically something that looks like cccccbcdgvvdrjgfnbeunhuutccliccrbtinukbjtknej)

This can be quite annoying at times, so you may want to disable this feature.
