The Thetis Pro-C FIDO2 Security Key is hands down the best security solution I’ve used for protecting my online accounts. Its build quality is top-notch, with a sleek metal design that feels durable yet lightweight. Setting it up was surprisingly easy—it works seamlessly with major platforms like Google, Microsoft, and even password managers like 1Password.The USB-C connection is fast and reliable, and the key has NFC functionality, which is perfect for securing accounts on my phone. I also love that it’s FIDO2 certified, ensuring the highest standard of security without relying on SMS codes or other outdated methods.What truly stands out is its consistency—it’s incredibly responsive and hasn’t let me down once. For anyone serious about safeguarding their digital life, this is a must-have. Highly recommend!

I think this key is the best bang for your buck compared to other brands especially because it's Fido2 with NFC.I skipped out on the more well known/popular brand because these are half the price and I wanted to buy 2.$50 for a main key and a back up is great considering this lil key could potentially save your bank accounts from being drained one day or scammers getting onto accounts with your card info.I also chose this key because I like the design and how it can be folded to cover the USB-C so you don't accidently bend it or something while carrying it around. You also don't have to worry about it falling out of the holder like the super tiny keys. So this one is great to have on your keychain.I use one of the more expensive keys for work and compared to this brand I would say set up and use if pretty much the same and it's very simple to use.For me, the only con to this key is that using NFC is kinda finicky. It's not that it doesn't work BUT with this one you have to have it held up to your phone precisely or it will not read. So that's kinda eh to me but I still love it.And for those of you who are new to using these, it's fairly simple to use even if you're not tech savvy. Scan the QR code on the device or got to their website and download their program so you can set your pin and then you're good to go.- Sign into the accounts you want to use this device with (not all websites support this feature yet btw)- open your security settings- set it up would just set it up as you would 2 set authentication. You should have the option to choose "physical key". Plug it in, type in your pin, press the lil button on your key and you're golden. You'll use that same method when you login.

I purchased this for my aging parents, I felt perhaps a security key was something to use to secure their information without my always having to be present. Keeping track of all their passwords and updating them and warning them about security was becoming a hassle. This has been a complete game changer, once I set it up on their PC, they are able to use it with minimal assistance on their own. They are not tech friendly people, yet this is easy for them to maneuver. Setup was straightforward and relatively simple, we've had no issues since they have been using it for well over a month, even traveling with it and they are happy to be more independent when it comes to their digital life.

the security key is reliable, and is actually compatible with linux mint xia(still untestested with the other linux distributions out there,so do your research before purchasing a security key for linux,because it is hit or miss depending on distribution support(linux distros can even include ChromeOS(which is the OS chromebooks run),Chrome OS Flex(a legacy/UEFI adapted version of ChromeOS for older PCs and MacBooks,does not support play store,google assistant and some biometric security hardware,some components like a CD-ROM will have partial functionality,some parts may not work at all),and Android(a very popular smartphone OS for alot of companies),those 3 despite being made by google,there is alot of linux distributions,those previously listed 3 are just a few examples,i personally reccomend linux mint)*i know this might start debate for some linux users,or start a ragebait(annoying someone by a subject while socalizing),so please do not get annoyed at me for saying a reccomended linux distrothere is alot of linux distributions,so hit or miss depending on linux distribution,saying "linux" compatability is talking about the platform(which there is a few main ones,those are debian,arch,and ubuntu as the common platforms a distribution is based on,noticed linux mint is kind of a hybrid of debian,arch,and ubuntu except for a special debian based variant,and ubuntu also has 6 variants alongside the main version),anyways keep in mind when "linux" is stated,that is talking about the type of OSthere is many distributions of linux,each one built different than the other,so support is not the same for each linux distributionalso untested with USB-C to USB-A adapters,so keep that in mind also,highly reccomend when connecting this to a USB-A or any kind of other port to use an adapter(untested) or USB-C PCI card for custom build/full-size desktops(i know this will work for full size desktops,does not work well if ports are tight together or you have a really wide subdevice/accessory to the computer port neighboring it without a extention(untested)does not work on a device with someone else's account as main account(standard for security keys)also don't know offhand if this works with microusb or lightning port devicesalso haven't tested NFC yetthis security key can work by just registering it to a account via account settings also,the OEM application is not nessisary

During setup my PC notified me that “Shenzhen Excelsecu Data Technology Co., Ltd” had installed items that would run in the background. This alerted me that this security key is made by a Chinese company. That destroyed my trust in it as security. I wiped the files and discarded the key.

Doesn't seem to work for Windows 11 passkey

Great price point and quality. Works with Windows11, easy to set up with provided documentation. The original fell out of the shirt pocket and got ran over by a tire
