Yubico Reviews

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

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.

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.

I did my order on December 7.
To date, I still have no idea where my order is and every time I contact the support they only send me an automatic answer where they talk about a generic delay.
UPDATE: I've been refunded and I bought it on Amazon (delivered in 2 days).

Recently got a Yubikey 5 USB with NFC. Adds a much needed layer of security to my most important on-line accounts. It can be a bit hard to get your head around what it does and why you should use it, but once set-up it is very easy to use and securing my on-line identities. There are some really confusing videos on YouTube and I don't think they help things with what they say!
I do wish more companies and agencies would support it, for example my bank, local government etc

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.
