I wonder if it would have worked to rub your finger off the side of your nose, or behind your ear? It's a trick some flute-players use for the pinky of the right hand, so that it works better rolling between the C, C#/Db and D notes on the bottom. I saw it mentioned in some tutorial once and thought: "no way", and was amazed at how well it worked. I never really asked myself how it works - something to do with skin on (dead) skin working up some friction, I don't know. I'd be curious to know if it would have worked with your YubiKey issue. But maybe it's too late to try now!
