YubiKey 5C NFC

The YubiKey 5 NFC is top-tier in its class: excellent security, broad compatibility, and great flexibility in connectivity. If you care seriously about protecting your accounts, it’s a very worthwhile investment. The trade-offs — cost, need for backup key(s), setup effort — are real but manageable, and in my view acceptable for the level of protection you gain.

Secure, cheap and works perfectly.

I have been after a security key for a while and I'm sure glad I went for this one. Easy to set up and use and compatible and connectivity across windows device and android phone is a big win for me also the ability to have a back up key made and stored. Quality feels strong and robust and there are plenty of covers available

The yubikey is small, thin and seems robust enough not to worry it dangling from your house keys. I heard mixed views on just how much or little you should look after it so I bought a case (just in car). I bought the USB C connector with NFC and a couple of adapters so that I could use it with my Android and my PCs. Despite my current version iPad with type C connector the key will not work with it (you’ll have to get the Lightening key and spend a further £30 on a Lightening to C adapter from Apple to get it working (how ridiculous is that?). They are, however, easy enough to set up but this varies with the service you’re using. Amazon was the easiest, followed by Google. Don’t think eBay support a physical key (despite Yubico stating they are compatible). Paypal definitely don’t (shame on them). The bad news is that I received the older firmware version (which cannot be updated). The new firmware was released in May 2024 and allows for 100 passkeys rather than a measly 25 for the previous version. There are other significant improvements too, so it’s not worth paying the same price for the old firmware. I contacted the seller after I received the keys to find out that they ship whichever version they happen to have. I then contacted Yubico via Amazon to confirm that they WILL supply the latest version via Amazon. Otherwise, I think this is a great product and wish more services would support it over software 2FA. It’s a very slow take up and some companies (including banks) do not support physical security keys. Some banks do have their own versions (HSBC) but Starling and ANNA Money rely on OTP via text (not secure). Paypal and eBay doesn’t support them either. There is a question of implementation by many services. Most insist on a backup to access your account should you lose your key. That’s great except it’s straightforward enough to just select that less secure option on login. I hope take-up will accelerate though as breaches seem to be on the increase. At least I’m covered when that happens.

The Yubikey is a very good very secure device but like anything in the IT security world, it takes a while to learn how to use it and set it up and of course the methods vary, depending on your device types. And buy two, you need a spare just in case you lose one. I use Windows and Android so I have the Yubico authenticator app on my phone and use that to access many of my accounts in the traditional way, by adding an authenticator app to whatever account I want to use the Yubikey to access. When the QR code is presented, with the Yubico app open on the phone and in the accounts page, I press the 3 dots top right then add account, scan the QR code and save the account by re-scanning the Yubikey. I DONT input the presented code to the account yet though, I REPEAT the process for my spare YubiKey's first then when I do the last key and the account is added to all the keys, then I complete the process by adding the one time passcode as requested. Easy! On my PC I plug the key into my USB port and input the pin that I setup using the Yubico authenticator app from Windows store, this way I have to physically touch the copper contact on the key to log into whatever account I have setup using FIDO in this case versus NFC that the phone uses. There are plenty of videos on YouTube showing how to set these keys up, it just takes a day or so to get your head around it if you are new to passkeys, but what's a day or so of learning for the extra security these keys give you? Lastly, some of the reviews are concerned about vulnerabilities in the older firmware but the two keys I purchased have firmware 5.7.1 which is the latest firmware. As for one reviewers post about a criminal running a program on your device, that assumes they have stolen the device AND KEY, can get past the device sign in security and also know the pin number for the key too which you should set for NFC and FIDO. If somebody has your phone, can access it, has your key and knows the pin to it, has your accounts and knows the usernames and passwords, vulnerabilities are already a moot point. These are very good devices adding a level of security that is just not possible with other 2FA methods.

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.
