U2F Keys from Yubico I think having this type of security (U2F Key) and replacing other methods is just excellent. Combined with a password manager like Dashlane for example is just top notch and definitely safe from attacks. It's an open authentication standard that enables internet users to securely access any number of online services with one single security key instantly and with no drivers or client software needed. They come in many sizes fit to the users needs, obviously make sure to have a few spare.

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

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.

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.

series 5 nfc buggy bought 2 series 5 nfc totally buggy to a point where yubikey-manager couldn’t read the seriol# of both keys anymore and AOL rejected both keys in that condition. support totally ignored my issues and closed my tickets before solving them How does anyone trust a company or a piece of hardware that buggy??
