Yubico - YubiKey 5 Nano C - Multi-Factor authentication (MFA) Security Key and passkey, Connect via USB, FIDO Certified - Protect Your Online Accounts (Nano USB-C)

The YubiKey 5 Nano C is an outstanding device—compact, reliable, and essential for security. It works perfectly and is barely noticeable when plugged into the port. I also want to highlight my experience with the seller and Amazon support. There was a critical delivery issue caused by the local carrier (Ninja Van), who failed to deliver to my address. Amazon was very professional, acknowledged the carrier's policy violation, and sent a replacement immediately. Surprisingly, both the original and the replacement arrived later. I contacted support to return the extra unit because I didn't want the seller to suffer any loss for the carrier's mistake. However, Amazon allowed me to keep it as a gesture of goodwill. Highly recommend both the product and this seller for their integrity and great customer service. Five stars!

This device delivers on its promise of easy, hardware-based security. It is reliable every time I log in, and the USB-C fit is perfect for modern computers. It supports multiple security protocols, which is very helpful for different work and personal accounts. I used it to secure my email and cloud storage first. What I wish was better is that there is no simple keyring hole like on other YubiKeys, which would make carrying it separately safer. It is still a top-tier security buy.

Awesome, compact, and does what it says on the tin. Would buy again, if slightly cheaper. Also is a real drag to lose (which i did), so don't take it out of the port unless you know where you are setting it down.

It's a Yubico product so it is built and works well. I'm going to knock off 1 star because the gold touch points are in weird locations. They sit on the top and bottom of the dongle. This makes touching them to complete the authentication sequence awkward. It would have made more sense to have a single gold touch point right at the end of the dongle so that a natural touching motion makes better contact. This is how the Nano with the USB A connector is designed which I find far more natural to use. It might be useful for some to know that this device is very small and designed to be placed in the USB port semi-permanently. It is difficult to remove and not well suited for transferring from device to device. If you're wanting something you can use on multiple devices then it is better to get one of the more traditional Yubikeys. The Nano models are really meant to just stay in the USB port long term.

Tried to use with Yahoo Mail, worked 1 time and now does not recognize key.

Got this because I have a mac and work required it for that platform. It is nice on the macbook because it has 3x ports so you're not stuck losing your only USB-C with it. However, on PC I would get the USB 2.0 / A version because those ports are a lot more prevalent and it functions exactly the same. The USB-C version is a little difficult to remove because it's so tiny and I need to keep my fingernails grown out to grab it.

I am a huge Yubikey fan and this it right up there the other 5 I own. this is standard USB C. This is not a negative, but if your hands are on the larger side likemine then the contact point are a little more difficut when it is connected to the USB port but knowing that I would still purchase again. I just have it plugged into a short USB extensio cable. This is a great option if you want to keep it connected to a laptop since it is such a low profile.

It fits nice and tight and is streamlined which is what I wanted for a MacBook, but I thought I’d be able to leave it in all the time and that’s not possible. It has to be reactive to accept a touch when need but if you are in other apps like email and you barely brush it places a bunch of random characters on the screen. I wish it had the touch mechanism in just one side so I would only reach it when I actually want it. It does work well though.

Chegou bem, lacre intacto d chave verifica. Está tudo funcionando perfeitamente

I won't mince my review of these: these are by far and away the best USB hardware crypto tokens I have every used. They can speak gnuk and ed25519, and thus can do the crypto for all your SSH logins and gpg, including git commits. Because of the hardware capacitive button, leaving them plugged in permanently is not a security risk, as even nation state actors who own your computer cannot physically activate the token. They work beautifully, without driver install, on Windows, Linux, MacOS and even Android and ChromeOS. In short, they are a one stop solution to all of it. That was the good. There is also the bad: unless you are doing U2P or Fido or something that the installed utility automates for you, expect to spend several hours researching the internet to figure out how to configure these properly. The documentation IS out there, but it's spread around, and there will be a fair bit of head scratching until you figure it out for the actually far more useful use cases which these will do, but for which nobody has automated the configuration for you yet. As much as all the manual configuration with gnuk, including telling the token to enable its capacitive button per gnuk crypto operation, is a pain, once it's done then it's done. The tokens "just work" thereafter. One major tip I learned the hard way: never buy one of these, always buy at least two. Configure both, and put one of them somewhere safe. Then if you lose the other one, or one breaks, you aren't locked out of *everything*.

小さくてずっと付けていられます。ちょっと高いけど

La chiave di sicurezza è perfetta. Piccola, discreta da non dare nell'occhio nemmeno quando viene toccata per farla interagire con il software. Anche lasciandola inserita per il periodo di lavoro, è difficile che qualcuno la noti. È di ultima generazione (FIDO2) per cui applica gli ultimi software di sicurezza ed è ottima come dispositivo per implementare l'autorizzazione 2FA. Quando non viene usata, basta metterla in un portafoglio dotato di cerniera. Prima usavo il modello che si poteva attaccare ad un portachiavi o da sole, ma davano nell'occhio date le loro dimensioni. Per l'utilizzo c'è poco da dire in quanto è semplicissimo: inserisci, tocchi ed è fatta e come suggerito è meglio averne due. Se una di rompe, la perdi o ti rubano il portafoglio è sempre meglio averne due registrate. In questo caso è meglio comprarne subito un'altra e registrarla, in modo da stare il minor tempo possibile con una chiave sola. Che altro c'è da dire? Ottimo prodotto.

The YubiKey 5C Nano has proven to be an excellent investment and serves as a dedicated backup key alongside a primary YubiKey 5C. The overall ecosystem is well designed, reliable, and materially more secure than app based authenticators such as Google Authenticator or Twilio Auth. It provides a level of protection and peace of mind that software based solutions cannot offer. For anyone seeking stronger account security, this is a highly effective solution. When purchasing a YubiKey, acquiring two devices is essential so a backup key is available if the primary key is lost or unavailable.
