Setup was quick and hassle-free, following the instructions on the website supporting popular services like Google, Microsoft or any online accounts. It’s compatible with FIDO2 for password less logins and works with older FIDO U2F protocols, too. Performance is fast and reliable, with no wireless vulnerabilities since it only uses NFC connection.it is a solid security key for anyone serious about protecting their online accounts. It’s compact, durable, and easy to carry on a key chain. The NFC feature works flawlessly with mobile devices—just tap to authenticate without plugging it in. I recommend this device to anyone who needs extra layer of security.

This is a solid choice for online security. It’s easy to set up, it worked seamlessly for me setting it up and the NFC feature is a nice plus. The build quality feels durable, and the added TOTP/HOTP functionality is a nice. My only gripes are the lack of USB-C support and the slightly confusing setup instructions for advanced features, but overall, it’s a great tool for two-factor authentication. Still for the money I give it five stars!

As a cybersecurity professional, I approve of this security key. It was very easy to setup and use. I love the fact that it can be used via usb, nfc and used as a TOTP or HOTP authentication device. Multifactor Authentication is pretty much a necessity in this day and age and this security key adds much needed security over using text or email as a 2nd method of authentication. It is smaller than a AA battery, light, and even has a loop for a keychain. It can be used with Windows, macOS, Android, iOS and Linux. Definitely recommended if you really want to secure some accounts.

I got this on the recommendation of one of my IT colleagues, and so far it's been pretty cool. It's a good size, smaller than the average thumb drive, and feels well-made. No issues with the software or setup; just follow the directions and it's pretty straightforward. I don't think I will use this with all of my accounts, but will definitely for some of my more important accounts that demand a higher degree of security. If you want to step up your 2FA game, this is a good option.

With all the phishing and scams, I needed to secure all my accounts. The Thetis security key is super simple to set up and use. Plug in via USB to set up and even works via NFC with phones. Great value for the product - small and easy to carry with the ability to attach a keychain. I've used other security keys and they are harder to use that they now just sit in a drawer.

Clearly states in the item description "linux compatibility" yet can't even set up FIDO through a linux or Android platform. So, you cannot do what you are advertising, or, in other words, lying. Don't buy this
