ThetisPro 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

I liked how well it works for a security key. It fits well in any of my devices as it has two sides for USB and USB-C. I have used it for a few months now and what I have noticed is that on my first month the USB-C end broke off. I was able to get a replacement and since then I have not had any problems with the product. I have not had any trouble saving keys. I like how cheap it is for saving data and has been compatible with all my devices that I have used so far. I use this everyday and do recommend for anyone looking for an easy solution to all your passkeys problems.

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.

I needed to get something on the budget and this more than served its purpose. Affordable and also allows you ease of access whether you use a regular usb port or usb-c So I am able to transition pretty easily between my PC and phone and that is magnificent. No worries about having an adapter ever.Even if budget wasn't an issue, I think I would still buy more of these in the future. It comes with a little keychain bag to protect it a bit from some water, dust and scratches. Makes it easy to carry with you. And overall I like this size because it is not as easy to lose. The ONLY step up for me at this point would be the yubikeys that allow you access to their authenticator app but considering those are expensive and it is really important to have a backup - this was a no brainer as I was easily able to get 2.This is pretty smooth. I have had no compatibility issues so far in apps I have used them in. The only thing is to be wary of using it on windows. It won't work until you authenticate it into your sign in.To do that, you go to windows settings -> account -> sign in options -> security key -> manage and it'll ask for your key. It should then ask for your current windows pin or password if you're using one. Then it should request to press the light of the key and that's about it. Once you set it up, it should work anywhere on said PC. From time to time it will ask permission and request your password again before setting up the key into new accounts as a security measure. But caution: do not reinstall windows or do a drastic windows recovery before a date it was setup on because otherwise it might delete your key data, which then won't allow it to be recognized and you might not be able to sign in if you have no other alternative. This is why I prioritize my 2nd key through mobile sign in whenever I can to prevent that. If you intend on doing a reset or getting a new PC, make sure to remove the PC key as your only form of sign in (accounts let you have more than one). Once you do your reinstall or change computers you can redo the setup otherwise you might end up making a horrible mistakeOverall this is incredible value and will be recommending this to others. I realize I've been to lenient on product reviews I feel like this is what an actual 5/5 stars is imo and I am surprised that it even has 4 stars over as of this time of writing

use it for fido2. it works well having both usba and c. Just kind of big and klunky. too big as a keychain. price is just right for features

Lately our business software has been wanting me to set up one of these. I am so computer illiterate! I'm doing it blindly so I hope I don't screw it up.I like that it's is also nfc activated. I try plugging it in my phone but it's not long enough with my case. Tapping it to my phone seems to work good.I'll have somebody help me to set it up but I'm excited to keep my business safer.
