Great product, well-built The YubiKey is a great product, very well-built. It's been durable and very quick when using via USB or NFC. I bought some more YubiKeys during the Cloudflare promo and they were shipped extremely fast from California to Florida. Happy with my purchases, this company cares about their users.

Their product didn't work Their product didn't work. Customer service offered a partial refund (excluding shipping costs). That's unheard of. When a product is returned, all payments are refunded and some will even send the client a free shipping label. When a product is faulty, that's goes without saying.

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.

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.

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.
