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.
This works (tested) on iPhones 8+ and 11 Max Pro. Both use lightening connectors, have not tested usb-C.
Apple ID Password can’t be changed without the device.
You will need two, keep in different places, in case of loss or failure.
DOES NOT WORK FOR USB-C ipad there is no key for iPad Apple ID protection.
Safety tips: Protect (hide) passcode, put your hand over phone to shield it like you would at the ATM. use faceID, when it works.
And to protect against SIM swaps, put a pin on your SIM. The provider default is ridiculous. Use 8 digits you can memorize. Need to enter this after shutdown at power up.
This will be my 2nd key. The Yubico 5Ci is very small, be sure to place a lanyard or cord through the small hole, something this small can get lost easy.
I wouldn’t recommend keeping something like this on your keychain, as the connectors are still exposed and can get damaged.
Ported over all my logins using the IOS app. Don’t be afraid to invest in this security key!, it’s better to have two. Works perfect with my iPhone ( you can assign two security keys to protect your account and phone ).
Works for my iPhone; iPad and Mac computers.
Some things are subtle like an LED light to show the device is working

すでに持っていたキーから考えるとこれ一本で対応できますが、PIN入力が少し面倒でした。
*Appleの場合、この一本では多認証の登録はできないのでご注意を。
Excellent produit de protection pour l’identification à double facteurs pour les réseaux sociaux et autres ( Facebook , Twitter , Instagram, Amazon , Google , PayPal , Apple etc….)
La meilleure protection en clé physique
Je conseil vivement d’en acheter 2 immédiatement afin d’avoir une clé de rechange dans le cas d’une perte de l’une . Vivement conseiller lors de la manipulation pour activation de ce type de protection sur les sites en question.
Excellent pour iPhone , iPad , Mac
Je recommande ce produit à toutes personnes souhaitant une véritable protection contre l’accès de vos comptes .
