Ever felt like disabling the output of a YubiKey so you won’t trigger it accidentally? If you’re a Mac OS X user, you’re in luck! Angelo “pallotron” Failla has written an application that runs on the OS X status bar that automatically disables your YubiKey after a period of inactivity.
Here’s a screen capture of how it looks like. It’s primarily designed for the YubiKey Nano, which is meant to be left in the USB port for long periods of time, but will work with the standard sized YubiKeys as well. Check it out here.
