## Customer Reviews

### ⭐⭐⭐⭐⭐ easily slips into your wallet
*by L***E on June 22, 2025*

I recently bought the FIDO2 Security Key and it's been a great addition to my digital security toolkit. Right off the bat, I loved how I could easily slip it into my wallet, thanks to its card-like form factor. Setting it up was a breeze, and I had it working with my Google and Facebook accounts in no time. The advanced security features give me peace of mind, knowing my accounts are better protected against phishing attacks. However, I did run into some trouble when trying to use it with my Android device—it didn't always work smoothly, but it was flawless with my Microsoft and Apple devices. Overall, the convenience and enhanced security it offers make it a worthy investment, even with minor compatibility hiccups. If you're looking for an easy-to-carry and robust security key, this one won't disappoint.

### ⭐⭐⭐⭐⭐ Great for iPhones...
*by S***W on July 20, 2025*

This is the "security key" to get for iPhone users. Tap and go. Very handy. A tip though: Use it on your Microsoft account first. They require a password. That way it will be all setup for everything else like your Apple ID. You may need their card reader to use it on your laptop. Actually, probably. Check that it has NFC. If not then get the reader. Worked with Microsoft Edge and Firefox. Didn't test on Safari yet but Apple is pretty good so...

### ⭐⭐⭐⭐⭐ Like an NFC Yubi key that plugs into a smartcard reader instead of USB
*by G***. on February 9, 2023*

Works with every FIDO2-enabled site I've tried it with so far.* Google* Microsoft* AWS* login.gov* GitHubThere are two models. The first one I got several months ago (left in the image) has a larger "chip" with 9 pads (I think). The last one I got (a couple of weeks ago) has a smaller "chip" with 7 pads.* The larger 9-pad chip worked with the most common smartcard reader I've seen (https://amzn.to/40Sax46), but didn't work with my Dell Latitude 5510's built-in smartcard reader.* The smaller 7-pad chip worked the Dell reader, the common reader linked above, and another smaller smartcard reader I tried (https://amzn.to/3YZipin)* When prompted to "tap or touch" the "security device", you'll instead remove the card (if inserted) and then (re)insert the card. That action ensures that you're physically present during the login session.NFC worked with my Google Pixel (Android) on both cards.* When prompted, you'll slide the card around the back of your phone until it beeps/vibrates/whatever, then try to hold it still until it says you're good. That action ensures you're physically present during login.Notes:* It's only useful with sites that support FIDO. There aren't a *ton* out there right now, but the "center of my life" sites like Google/MS do, and they're *way* more secure than user/pass alone. It'll catch on, though, and more sites will support them as time goes by.Incredibly useful when working somewhere where:* You can't have your phone on you* You can't have anything that even *looks* like a USB flash drive on you* There are smartcard readers at nearly every computer* You've turned on 2FA for your Google account (as it should be) and need to log in
