YubiKey 5C Nano

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.
