FIDO Works Good!
The software from thetis.io/start to setup the security key is a little confusing since it covers two devices, the security key and the finger print scanner! just run the downloaded .exe file as administrator, and plug in the key and the software recognizes the key then click on FIDO and set your PIN. the rest of the instructions are good.

Simplifies Multi-Factor Authentication with Easy Setup
This device has been a great addition for managing multi-factor authentication on some of my devices. The setup process was incredibly simple, making it very user-friendly even for those who aren’t tech-savvy. One of the best things about this product is its small size, which makes it easy to carry around and use on the go without any hassle. It operates seamlessly and has made my login process more secure and efficient. Pros: The compact design is a major plus—it’s small enough to keep on a keychain or slip into a wallet. The operation is straightforward, making it accessible for quick use without any complicated steps. Cons: The only downside I've noticed is that it feels a bit flimsy. While it works perfectly fine, I would have preferred a more solid build to give it a more durable feel. Overall, it’s an effective tool for anyone looking to streamline their multi-factor authentication process. I highly recommend it for its convenience and ease of use!

Useless
I vet in the VA using ID.me. I was a mainframe sysprog. If you are a Windows user, make sure you have RUN AS ADMINITRATOR in your context menu otherwise the device will not initialize, and you will be up the creek. I returned mine because it was useless.

Great value and works great
I bought this to avoid having to use my phone all the time for certain MFA at work and it works great. I also set it up for use with other websites as well. Very happy with the price and i like that it has a covering for the part that goes into the computer.

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.
