Review: Secure, Versatile Multi-Factor Key with Broad Compatibility and Practical Use - I am very pleased with the Yubico YubiKey 5Ci. Shipping was prompt, and the security key arrived well-packaged and protected, with no signs of damage. The dual-connector design—featuring both USB-C and Lightning plugs—was exactly as advertised and ready for immediate setup. In terms of product quality, this YubiKey feels solid and reliable. The build quality gives confidence that it will withstand daily carry on a keychain, and the connectors seat securely into devices without wiggle or looseness. Setting it up with my accounts was straightforward; the configuration steps were clear and compatible with the MFA options in most services I use. Functionally, the key enhances security through hardware-based authentication rather than relying solely on passwords or SMS codes. It supports modern authentication standards such as FIDO2/WebAuthn and U2F, providing a practical second factor for logging into email, cloud services, password managers, and other online accounts that support security keys. The dual Lightning and USB-C connectors make it especially useful for iPhone users and other Apple devices that lack conventional USB ports. Yubico +1 From a value perspective, this security key offers strong protection at a reasonable cost compared with subscription-based alternatives or more complex enterprise solutions. Its broad platform compatibility—covering iOS, macOS, Windows, Linux, and many web services—adds versatility. While not every app supports hardware keys yet, the ecosystem continues to expand, and the YubiKey remains a robust, future-oriented investment in account security. Overall, this is a well-made, dependable MFA solution that combines convenience with significant security benefits, and I would confidently recommend it.
Review: You may not need a lightning plug for much longer - this one is very expensive for what it is - 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.

## Questions & Answers

**Q: How do you recover your ability to log on if you lose the key?**
A: Make sure you save the recovery codes when you set up 2FA / MFA.

**Q: Do the connectors retract?  Looks as if they could be damaged carrying on a key ring in your pocket.**
A: They do NOT retract, overall seems sturdy, I keep mine put up at home with a back up key in a safety deposit box at the bank. To make a copy after capturing the QR code with one key and saving the info, simply pull the key and stick the second one in and capture the same QR code, boom two copies, can do same with 2fa apps, the key is the same QR code, means same gateway sorta speak.

**Q: Does the yubi remained plugged into your device/pc the total length of time you are using device/pc, or do you unplug it once authenticated?**
A: For OTP/U2F you only need it plugged in when you're prompted for the token (ie U2F on Github, Facebook, Google, etc.); It is a good security habit not to leave it plugged in. Yubikeys have many uses and while I don't know of any that require the Yubikey to be plugged in to maintain access you can use it as a "Smart Card" for logging into your computer (ie if the screen locks or you logout you will need it to log back in).

**Q: Does it work on 2020 ipad**
A: Yes. The iPad Pro uses the USB-C connector. The regular iPad uses the lightning connector

### ⭐⭐⭐⭐⭐ So versatile across all my Apple devices!
*by S***R on August 14, 2025*

This little powerhouse works on all my Apple devices, macbook iPad, iPhone as it handles either USB C and lightning connections! Everyone knows YubiKey for it's strong security. The delight to this 5Ci model is that I works on all these devices. Of course, it works on Windows and Chromebook too, where you might already have a USB C connector, but if you only have USB A, you can separately buy a standard USB C to USB A adapter and it works the same! Use it, don't lose it!
