Amazing product for the peace of mind in the online space
Let me tell you, the FIDO2 Security Key by Thetis is an absolute game-changer! I was stressing over potential cyber threats messing with my online accounts until I stumbled upon this. Setting it up was a breeze – clear instructions and seamless integration with all my accounts. Within a week, the cyber world went from chaos to calm, thanks to the added layer of security this key provides. What really impressed me is its compatibility with all my online platforms – emails, banking, social media – you name it, this key works with it. Plus, it's built tough, so no worries about it giving up on you. Furthermore, the performance is amazing. This makes it easy to use. Just plug in press the button on the key and there you go, you are logged in. However, if you are looking for this to unlock your pc as a physical key on the lock screen of the pc, this isn’t the key you are looking for. This is because it doesn’t work for that but only for online accounts and other use cases. If you're serious about online security and want some peace of mind, do yourself a favour and grab a FIDO2 Security Key. Trust me, you won't regret it!

Amazing
I recently purchased the Thetis Aluminum FIDO2 Security Key and I have been extremely satisfied with my purchase. This key is an excellent tool for increasing the security of my online accounts. It uses FIDO2 technology, which is a widely accepted and secure standard for two-factor authentication. One of the standout features of this security key is its durability. The aluminum casing is very sturdy and has held up well to daily use. The key is also very small and portable, making it easy to carry with me wherever I go. The setup process for this key was very straightforward, and it was compatible with all of my online accounts that support FIDO2 authentication. I have noticed a significant improvement in the security of my accounts since using this key, and I have peace of mind knowing that my accounts are much less vulnerable to hacking attempts. Overall, I would highly recommend the Thetis Aluminum FIDO2 Security Key to anyone in need of an effective and secure two-factor authentication solution. It has proven to be a great investment and has exceeded my expectations.

Okay
Works perfectly, only thing is it doesn’t fit on my waist lanyard keyring properly as the hole is a bit small. Offers great security. Bit expensive for what it offers though. Easy to use once set up, but when first bought you need to download apps, give them administrator permissions and all sorts as well as then going onto your accounts and adding the security key.

It works exactly as expected. Good value.
Easy to set up for this intermediate PC user. Works very well at logging in the computer it was set up for. It would be great if they made them in different colours so I could colour code them to different PC's.

In my opinion, Better than Yubico keys
I had purchased and used 4 Yubico keys before I bought my first Thetis as I ran into an installation issue with one application with my Yubico keys. With my Thetis security key, I resolved the aforementioned installation issue. Furthermore, I have managed to register my Thetis security key with all the relevant applications/sites as a backup security key. It is cheaper and sturdier than Yubico keys. I definitely recommend this.

No issues so far!
My first security key, seems to work just fine, easy to setup, cant complain for now. It is all made of plastic though so durability might be an issue later down the line.

This can only be used on the one computer used to register it.
This can only be used on the one computer used to register it. This is not mentioned anywhere. It's easy to use once setup but I found the installation a bit of a faff. It is the size of a small flash drive and seems quite durable. As to its security I hope it is as good as a passkey and better thana password.

hardwaresleutel met redelijke prijs
niet al te dure hardwaresleutel voor extra beveiliging, werkt voor mij op zich prima met websites die dit ondersteunen, zoals ook Amazon :-) Afhankelijk van het OS dat je gebruikt kun je er meer of minder mee doen op systeemniveau.

Does not support many websites currently
I bought this as a backup to my Yubikeys. I should have researched more about before buying. Currently very few websites support Thetis FIDO2. I do not recommended buying this as your first security key. It's not good value for money at this stage.

Robusta, práctica y perfecta para reforzar la seguridad IMPRESCINDIBLE
La llave FIDO2 de Thetis destaca por su diseño plegable en aluminio, que además de proteger el conector la hace muy cómoda de llevar en el llavero. La autenticación funciona sin fallos: se reconoce rápido, no requiere configuraciones complicadas y añade una capa de seguridad real frente a contraseñas débiles o phishing. La construcción se siente sólida y el mecanismo de apertura es firme. Una opción fiable y bien diseñada para quien quiere mejorar su seguridad digital sin complicarse.

For Bank of America
Bought it to transfer fund from Bank of America since I do not have a USA mobile number. No set up needed just login into BOA account and insert your FIDO2 key and it’s set up and recognized. Easier than what I imagine. Works very well for those who wanted for this purpose.
