Thetis Pro FIDO2 Security Key, Two Factor Authentication NFC Security Key FIDO 2.0, Dual USB A Ports & Type C for Multi layered Protection (HOTP) in Windows/MacOS/Linux, Gmail, Facebook,Dropbox,Github

This security key is very easy to use. I used it to set up Passkey security on my Gmail account on my Windows 11 PC. To do that, here are the steps I used:1. I went to the Thetis web site listed in the instruction manual and downloaded the Thetis Key Manager.2. I then started the Thetis Key Manager in Administrator Mode. It tells you to insert the key in a USB port. You have the choice of USB-C or A.3. You're then presented with a list of options, some based on different Thetis devices. For my test I selected FIDO.4. You then are instructed to set a PIN. It doesn't tell you the minimum number of characters to use. I first used 4 and it failed. I then used 8 characters and it succeeded. You can then close the app as you're done with it unless you want to change the PIN.5. The key has 50 slots, according to the product page, which means you can secure up to 50 apps or sites with the key. The instruction manual says it has 200. At any rate, it's a lot.6. In my test, I wanted to secure my Gmail account with the key. To do this, I went into my account and clicked Manage Your Google Account...Security...Passkeys and Security Keys.7. You're then prompted to enter your Gmail password.8. From there, you then click Create A Passkey twice on 2 screens.9. It then prompts you to plug in your key and press the button when prompted.10. Your passkey is then registered for Gmail on your security key.I've listed the steps in detail but in reality it's pretty simple and fast.From then on, any time I need to log into my Gmail account I'm prompted to plug in the key. The process works well. The device itself is well constructed so it seems it is built to last. The included instructions are sufficient to get you started. It comes with a little pouch and keychain you can use to carry it around. It would seem prudent to get a second one as a backup in case you lose or break one.All in all I'm very happy with this security key. The price is very reasonable compared to other security keys on the market. It's easy to use and works well.

This is a huge plus for anyone with devices lacking USB A or C connections.While iOS and Android devices have some limitations, the mobile app and downloadable software for desktops make the key even more convenient to use. The security it provides through two-factor authentication and 50 passkey slots is fantastic. It’s sturdy with a solid metal design and comes with a nice carrying case, making it feel much more durable than other FIDO2 options.Although it’s not the cheapest option, the price is reasonable for the quality you get. The lack of wireless features like Bluetooth makes it feel more secure, ensuring there are no concerns about wireless vulnerabilities.
