SecuX PUFido USB-C Security Key with PUF Technology, FIDO2/U2F Certified, Hardware-Rooted Unclonable Security for Passwordless Login and 2FA Authentication

I picked up the SecuX PUFido USB-C Security Key to add some extra protection to my online accounts, and I’m really happy with it so far! It was super easy to set up — just plug it in, follow a few simple steps, and it works right away with my Google and Microsoft accounts. The USB-C connection is great for newer laptops and phones, and it’s super fast when logging in or verifying my identity. I love that it uses special PUF technology, which means every key is unique and can’t be copied or hacked — it makes me feel a lot safer using it for my logins. The key itself feels sturdy and well-made, but it’s small enough to keep on my keychain. I haven’t had any issues so far, and it works perfectly every time. If I had to nitpick, it’s that it only has a USB-C plug, so you’ll need an adapter if your computer only has USB-A ports. Not a big deal though. Also it doesn't work with every website. Overall, this is an awesome security key for anyone who wants simple, reliable protection without any tech headaches. Totally worth it for the peace of mind!

I absolutely love this security key. The setup was quick and effortless, and it worked right away with all the accounts I tested it on. The USB‑C connection is super convenient for my devices, and authentication is fast every single time. The build quality feels solid, and the PUF technology gives me real confidence that my accounts are protected with hardware‑level security. It’s small enough to keep on my keychain, but powerful enough to handle password less login and 2FA without any hassle. If you’re looking for a reliable, easy‑to‑use FIDO2/U2F key, this one is a fantastic choice. I’m really glad I bought it.

I am surprised by how simple this device is to use. I had assumed there would be more required to get it set up but there is nothing required. It is super easy to use it! I have heard about security keys before and I am glad I finally decided to try one out myself. I plan to continue to use this device to keep my online accounts secure. It's nice to not need to worry about remembering which of my accounts have which password. I feel like this device would be great for anyone who has alot of online accounts with too many passwords to keep track of. I have already recommended this device to a few of my friends that I thought it might also find it to be helpful because I think its convenient to have and super easy to use!

You cannot use on mobile device, I was even unable to set up on my computer. It had me set up a pin then next time I went to sign in it didn’t ask for the key. Basically useless.

I recently purchased the SecuX PUFido USB-C Security Key and I couldn’t be happier with my decision. Setup was quick and effortless, and it works seamlessly with my Google, Microsoft, and Facebook accounts for passwordless login and 2FA. The build quality feels solid and durable, and the compact design makes it easy to carry on my keychain.

I watched a YouTube video to see how to use this security key. The instructions seemed easy enough but I kept struggling. I finally used my laptop to set it up. It was truly easy doing it that way. Then I was able to use it across my other phones and tablets. So many apps, especially email, and websites almost force you to use the 2 step verification method when logging in. And using the passkey worked great. Wish I had tried this sooner.

Seamless and easy integration with existing MFA systems. Good buy

Reliable. Easy to use. Fits both iPhone (take off any case holding phone or it won’t connect. Cases too large for key connect), great value for money. I would rate 5-stars if key fit with phone case on. Key insert point needs to be longer.
