Yubico - YubiKey 5Ci - Two-Factor authentication Security Key for Android/PC/iPhone, Dual connectors for Lighting/USB-C - FIDO Certified

I bought this specifically for the dual Lightning and USB-C support. I’m currently using an iPhone 14 with the older charging port, but I plan to upgrade to the latest iPhone soon, so I wanted a key that would work with both.It’s been easy to use, very functional, and gives me peace of mind knowing my accounts are more secure. I love the concept and highly recommend it to anyone looking to step up their online security.

I don’t know if I reviewed this already or not. Guess not. This works great. You MUST buy two though. You keep one in a safe place at home, and carry the other one around with you. I tied a tiny piece of ribbon on each, different colors, so I can tell them apart. It works great. I haven’t had any problems, so I can’t say anything about customer support, sorry. I keep the one I carry around in a little case, and put keychain things on that. I did all that because it is so tiny, I would lose it if I didn’t.

I recently got my YubiKey security keys for my online accounts' setup. A couple of things I learned:(1) For Apple icloud 2FA purposes, you need minimum of 2 keys so I wish I’d bought a second one upfront.(2) As a first-time user, I found the setup a bit confusing at first. I thought the key would work like a USB drive, but you actually need to touch the metal contacts on the sides to activate it. Once I figured that out, it worked fine. It’s a solid option for extra security, though it takes a moment to get the hang of it.

The product itself is A++++, 6/5 stars, highly recommend. BUT: because this is tamper-resistant hardware, you cannot upgrade/update the firmware. The version you get is the version you will always have. The latest version 5.7+ is the firmware update that takes your Fido2 credential capacity from 25 accounts to 100 accounts. This is for 5.7+ only, meaning if you buy from Amazon like I did there is no guarantee you’re getting the latest version (like in my case). Therefore when you read specifications for yubikeys always remember that they are firmware version specific. They cost the same exact price as they do on Yubico, so why not buy there? If you buy here your getting 1/4 the capabilities of the device for the same price. Also I was sent one with only the lighting end functioning and c end broken. Got a new one but still with outdated firmware. Product is still great I just don’t see this disclaimer anywhere on this site so I will be the one to make it.The firmware is non-upgradeable, by design, and for good reasons. Therefore this product should not even be listed on Amazon, don’t make my mistake. Go to the manufacturer to purchase

After having an account hacked and researching ways to make them more secure, I learned about security keys. I feel a lot better about my info along with my accounts for having another way to protect my stuff but I do think that this was on the more expensive side. I wish it was bigger as it can be lost easily. I also wish it came with directions as I am a first timer with security keys. All in all, I recommend buying one if you want more security

You can mute, turn off, not allow -etc etc , but that will not stop someone from listening to your every word! Really - it happens , it happened to me , and utilizing weak security protocols from my FORMER cell provider , my entire identity was stolen by someone access my phone illegally, one they captured my passcodes via my camera and my information thru 24 / 7 ease-dropping, by the time it was discovered it was too late , I would not dare allow anyone to use a phone in my home , or around me without this security key paired with a NFC card - it works and my hackers tried to disable it remotely with no success! I keep extra ones that I let people around me use to keep our passcodes private , at my house you can leave your phone in your car, or use the mic-Locke! Once soneobe gains access to your camera they can see your passcodes or your s keystroke counter to learn it, in real time I was able to screen record a hacker using my user id and passcode, but once I added the NDC card with a second security key , they could not use the passcode alone, they had to have the physical card and key or it would not allow access. A must have for todays AI -black hat hacker world !!! Nite that Apple phone will require 2 keys -at the same time as your must have a backup , a safety measure to ensure you do not lock your self out of your phone - I did not know that until I stated to use , I hope that messengers conveyed , I added a NFC card as my second key .

Per my bank, I was told to use this device. I tried, with the help of Apple, three different Customer Service representatives, escalated; after this device did not work on my iPhone 14 Pro; I requested a return. Amazon was so helpful and professional about the issue; and allowed me to return it for a full refund! Five Stars ⭐️ for Amazon, 1 Star for the device!
