I got a Yubikey in January, but as far as I remember, there was no smudge like this on it 🤔

Hmm, maybe it's from some kind of manual testing/QA in the manufacturing process? But I'm just speculating.

@flauschzelle Yeah, in my support request to Yubico I'm asking that exact thing. Really interested in what they're gonna say.

@scy I have indeed. And, no, even though I wasn't totally convinced that the packaging couldn't be tampered with, at least I didn't see anything obviously amiss.

Also, kudos to Yubico for having a page like https://www.yubico.com/support/shipping-and-buying-information/packaging/ where you can see how the packaging is supposed to look like, and some basic advice on how to spot tampering.

@scy you sure thats a finger print? Could also be the packaging sticking to the machined surface of the button.

@maxheadroom That touch surface is inset about a millimeter deep, and the blister plastic is quite stiff. I can't even make it touch the gold surface if I push on it. With enough force it might be possible, but that would leave a probably permanent dent in the plastic.
