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)

I had trouble with leaving my full sized yubikey in the machine and I don't like plugging it in and out so I just got this thing. The one I had before was issued from an employer so I did not have a choice of form factor. It works fine, just like a full sized model. You can remove it but it takes a little effort so it is not going to fall out. Having the small form factor like this is so much nice than that other one flapping around. Whoever designed this got the parameters and usability just right.

Works perfectly with iPhone and Mac

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.

Nice encryption key. It fits nice and flush against a cell phone, however, this same feature, and how tight the USB connector are make this easy to lose if you are trying to remove it from your cell, and your hand snaps and looses grip. Since it is so small, it is hard to grab onto on the bottom of a cell phone. You may need to reengineer (cut up) your cell phone protector in order to make this easier to insert and remove. Don't worry, it is a right of passage, and most people that use these kinds of devices have the same "homebrew" modification. Web site compatibility is good with webauth, but many sites do not support this, including many banks and credit unions. Social Security and Medicare both support the yubikey, as do most stock trading sites and security oriented web sites like VPN web sites.

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.

Does what it advertised. Barely notice it is there

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

This is not “key” concept solution, it’s more “sick and go” thing. On ipad this thing can make life harder: it’s keyboard device- so it’s blocking onscreen keyboard + you can pasting random text in everywhere with just touching.

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.
