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 ;)

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.

Ordered a product 17 days ago 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.

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.

Yubico's prompt refund I have a higher import duty issue with UPS carrier for an Yubico order and requested them to cancel after 5/6 days. They cancelled and refunded promptly.
