YubicoYubiKey 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.

This one is a bit pricey but it necessary if one still has an older ipad without USB-C. It works well. Apple has finally made their ipad USB-C port compatible with yubikey, I haven't tested that. I have used this key with windows and Mac PC's, as well as with an iphone and it works easily and well. I also own a USB-C NFC and that also works easily, except with an old ipad. You need to have at least 2 keys in case one gets lost, and I recommend that the second key be a cheaper version as you don't need a complete drop-in replacement you just need the backup key to add a replacement key.You should know that using a security key to lock down an apple account means that you lose the ability to ask Apple to unlock your account should you lose your yubikey, which can be a big deal. Other accounts are not as strict and treat the yubikeys as just another second factor. This is a complicated product and I am enjoying getting to learn about using it. Yubico has great support materials on their website and good links to external sites for various accounts and services you might use their key with.Since this version is pricey (about $25 more than the USB-C/NFC one), I would recommend only getting one of these, and then a cheaper different yubikey as a backup. The backup device is only necessary if the first gets lost, and once you replace the lost key you only need the backup on one device to do the task of adding the replacement key to all your accounts. This is a bit cumbersome but hopefully it'll get easier with time.Last thing - this key has it's keyring hole in the center, which works surprisingly well; it sits on my keychain nicely even though I worried it wouldn't.TL;DR - great product but security keys can be "dangerous" and are not for everyone. This one is pricey because it supports an edge use case (old ipads).Edit to add—I also own a USC-C NFC version of yubikey, which is similar to this product but is cheaper. I wanted to add that the lightning/USB yubikey is my favorite form factor as it is much SMALLER and I also prefer the activation mechanism of pinching it instead of touching a metal front.

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 .

Peace of Mind! Easy to setup and manage. Easy to use and be secure. Works with multiple devices, websites and apps.

I bought this for use with my iPhone and MacBook Pro. I'm particularly fond of the hardware multi-factor authentication feature of this device that works in conjunction with the Yubico Authenticator app for Mac/Windows/iOS.For the cons, it doesn't work with the USB-C port of the iPad Pro and the price is a bit steep.

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.

I was told this is like one of the best securities you can get for your passwords. This thing never work from day one I would not recommend it.
