Silence. Ordered on October 13th, received a tracking code from UPS and since several weeks no news! I will update this notice if I ever receive my order.

Order never shipped. Company unresponsive. Ordered end of October. Almost January and no shipment. No response from company at ALL. No stock on Amazon. Either they're having serious supply issues, or they're just a non-existent company taking money for no services.

I purchased 2 yubikey devices in May I purchased 2 yubikey devices in May, paid for express delivery, and still waiting for the devices to arrive at mine. I have tried to contact them via tweeter and emails but no headway so far

Ordered a product 17 days ago Ordered a product 17 days ago, put in an inquiry at the 2 week mark as to its whereabouts and still no updates. For a product thats advertised to arrive in 5 days. no updates/ apologies, its not really what you would expect. Feels more like a scam.

Using Yubikey introduces the risk of the rightful owner of account is prevented access. It is a problem that Yubikeys cannot be duplicated for backup. They are so secure that even the owner of an account can be locked out, lol. That's not good. In case of lost key or hardware malfunction there is no way to access your account. Unfortunatly two different keys often cannot be registered for the same access. Using Yubikey introduces the risk of the rightful owner of account is prevented access.
