YubiKey 5C NFC - Two Factor Authentication USB and NFC Security Key, Fits USB-C Ports and Works with Supported NFC Mobile Devices - Protect Your Online Accounts with More Than a Password

Easy to use with no real issues. It allows me to log into important accounts using a PIN, which is really handy. My only gripes are the price and how small the device is. It feels like good quality though—durable enough with responsible use. I'd recommend having a lanyard, or something, to reduce the risk of losing it.

The Yubico YubiKey 5C NFC is one of the best purchases I’ve made for online security. Setup was straightforward, and once configured, it adds a serious extra layer of protection to accounts. I love that it supports both USB-C and NFC, so I can use it with my laptop and just tap it against my phone when needed. It works seamlessly with major services and gives real peace of mind knowing my accounts are protected by hardware-based two-factor authentication. The fact that this pack includes two keys is brilliant — one to use daily and one as a backup stored safely. The build quality feels solid and durable, not flimsy at all. If you take online security seriously, this is a worthwhile investment. Reliable, easy to use, and far more secure than relying on text message codes alone.

Works flawlessly and feels very secure, but setup can be a bit confusing for beginners. Once configured, it’s extremely convenient and fast.

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.

Secure, cheap and works perfectly.

Unfortunately some providers are still lagging behind with the option to use these for authentication but for the ones that do these are fantastic. Very simple to use, just took a little while to figure out the most reliable place to hold against my iPhone 13 Pro Max. Presumably newer phone models will be less sensitive. Build quality is excellent and gives confidence that it’ll still work when you really need it.

He estado usando la Yubico YubiKey 5C NFC durante varias semanas y ha sido una mejora clara en mi forma de gestionar la seguridad de mis cuentas. La configuración es directa: conectas la llave a un puerto USB-C o la acercas al teléfono con NFC, sigues unos pasos cortos con cada servicio compatible y listo. La integración con servicios populares como Google, Microsoft, GitHub y administradores de contraseñas como 1Password es muy sólida. Lo que más valoro es que elimina la incertidumbre de los códigos SMS o las autenticaciones basadas en aplicaciones que dependen de una red o batería. Es una seguridad de segundo factor real y física, que simplemente funciona. La construcción es robusta, compacta, fácil de llevar en un llavero y no requiere baterías ni conectividad activa. Para quien prioriza proteger sus cuentas crítico (correo, finanzas, nube, contraseñas), esta YubiKey aporta paz mental y fiabilidad. Si estás dispuesto a invertir en tu propia seguridad digital, es difícil encontrar una opción más fiable y estándar en la industria.

Je voulais franchir le pas pour sécuriser sérieusement mes accès et cette YubiKey 5C NFC est vraiment l'outil parfait pour ça. Ce qui surprend au début, c’est sa taille : elle est minuscule et ultra légère, mais on sent tout de suite que c'est du solide. Elle est faite pour rester sur un trousseau de clés sans craindre les chocs ou la poussière, c'est du matos quasi indestructible. À l'usage, c'est d'une simplicité désarmante. Sur l'ordi, on la branche en USB-C et un petit contact tactile suffit pour valider la connexion. Sur smartphone, c'est encore mieux : avec le NFC, il suffit de l'approcher du téléphone pour que ça soit reconnu instantanément. Ça change la vie par rapport aux codes SMS qu'on attend ou aux applications d'authentification qu'il faut ouvrir toutes les deux minutes. C'est vraiment rassurant de savoir qu'on a une clé physique pour protéger ses mails ou ses comptes les plus sensibles. C'est propre, hyper pro et surtout ça fonctionne partout sans bugger. Un petit investissement pour une tranquillité d'esprit totale au quotidien.
