Absolute disaster Absolute disaster. Stay away. No customer service. Yubikey does not work well with Google Chrome and windows 10. I was locked out of all three of my crypto trading accounts after the first day with an error message on all three that said my device was not recognized by windows Chrome security and to try another key.

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.

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.

Just works After being recommended by a friend, who has a PhD in Ai field, I got 2 (YubiKey FIPS Series) for myself. One for use and another for back-up if things go south. It has given me great mental peace. The device is small, easy to carry and very efficient to use. I am happy to have them around and working on the security problem. Recommended.

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.
