Solid 2FA I have been using the YubiKey for over 2 years now and it has saved me and my company from potential damage on multiple occasions. Just make sure to never lose your key ;)

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.

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??

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

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.
