UK customers - Beware the artificially high shipping fee I placed an order with Yubico. They charged EUR15 for shipping. My order was delivered by Royal Mail Tracked 24 service. According to the Royal Mail website, this cost Yubico GBP3.30 for an 80g shipment weight as declared on the Royal Mail label. This means Yubico have charged an artificially inflated price for shipping (GBP3.30 is EUR3.75, which is substancially less than EUR15)

Stress-free 2FA I've got two Yubico Security Key NFC keys and the build quality is excellent. They've been pain-free to set up on all my devices and with all of the online accounts that supports them. It might be worthwhile checking which services support specific Yubico keys before buying them so you won't be disappointed, since it varies depending on the model you buy. These keys have been great for my personal use and the companion app, YubiKey Manager, is nice and simple to use.

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

This is the 3rd key from this company, what a nightmare This is the 3rd key from this company. It was simple enough at first but since buying one for my Android phone via USB-C it's been an hour now and I still can't work out how to register this and copy my sign-ins over from my other keys. Why can't they make it easier like cassette to cassette copying? remember that anyone? Why not have a one-click or two program that copies one key to the other instead of a load of complicated instructions? Beam me up Scottie.

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.
