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 ;)

Non Existent Customer Service - Also Just Plain Rude Shockingly bad, full-friction customer journey. Customer Service is non-existent for all practical purposes including initial purchase. I wanted to spend 15 minutes buying these security keys - I'm at the end of day 2 now and still haven't made the freaking purchase due to non-existent help from Yubico and their so-called resellers in the UK. The resellers don't actually sell anything, they refer you on to someone else. If you want to get a freaking headache then please go ahead and start your journey with these unhelpful, rude, time-wasting, arrogant people.

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.

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??
