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.

Bought 2 of these, couldn’t decide if to get the nfc version or not but did. Using the nfc on my iphone 16 works on the first tap but never on the second tap to authenticate. I always end up plugging it in. Other than that works as it should, more than enough storage for me and feel a lot more protected.

Before first use test of nfc doesn’t work. The latest firmware keys with firmware 5.7.4 will not work using nfc as it’s a security feature. It’s best to ensure before plugging in as it’s a surefire way of knowing it wasn’t previously used. Go to the official yubico authentication site on a mobile phone. It will ask to touch your NFC enabled device for authentication purposes and to tell you what firmware it is on (firmware cannot be changed or updated so latest is v5.7.4.). It will not detect your Yubikey. That means it’s never been used. Then plug it into a usb c powered charger or a port on your phone or laptop. Anything that will provide power and you will notice the Yubikey logo will flash yellow for a few seconds. Once flashing is stopped. Go back to the site and verify not only its authenticity but that you have the latest version as it will show firmware etc. I had the latest device so safe to get these from Amazon as they are supplying the latest stock. I will buy another which is essentially as a backup since you cannot unfortunately clone these or act as passkeys that have the ability to backup and transfer so keep that in mind. In fact companies like Apple accounts will require two types of these keys to even use them for multi factors authentication on the account and go passwordless. Very expensive but made in swish and America exclusively so makes sense. Very good build quality. Super easy to setup as during the authentication process on yubicos website will make one for you and even guide you to how it works etc. very easy. It has a large capacity in terms of storage for different apps/sites/accounts to be enrolled in it and magament is easy with an intuitive app plus desktop version that’s even better. Highly recommend getting a pair of these in this day and age with ai guessing passwords in seconds using brute force. More and more companies are offering this type of authentication tools so it’s easy and convenient with nfc and usb c so covers everything from older iPhones without usb c and just better for port wear and tear etc.

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.

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

Already spent too long trying to convince my computer its changed my keyboard to a US layout to start the process. Unless there is a European equivalent then dont waste time purchasing.

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.
