Review: Hat mir gefallen - Sehr gute produkt,ich kann ihnen empfehlen
Review: Seguridad hardware de código abierto - Llevo varios meses utilizando mi OnlyKey a diario: con KeepassXC para gestión de claves y para conexiones SSH. Al principio tenía algunos bugs pero tras algunas actualizaciones ahora todo funciona perfectamente. La he usado alguna vez conectada a mi teléfono móvil por USB OTG, pero es algo muy esporádico y es un fastidio tener que andar con un adaptador de USB-A a USB-C. Aprecio mucho que el software para usar la llave sea libre, por un lado me ha permitido arreglar personalmente algunos bugs que me he encontrado y por otro siguen llegando nuevas funcionalidades (como soporte para firmado con claves PGP/GPG). Hay mucha flexibilidad para usar la llave en muchos escenarios diferentes. Un detalle importante sobre esta llave es que las claves privadas no están protegidas contra ataques contra el hardware interno, porque está basada en Arduino y no dispone de un elemento seguro. Esto significa que si alguien se apropia de la llave y dispone de suficientes recursos (miles de euros en equipamiento especializado) probablemente podría extraer los datos. Si este es un vector de ataque del que necesites defenderte entonces mejor busca productos con un elemento seguro que se haya probado resistente contra ataques (aunque en estos casos tienes que confiar en los fabricantes, que no tengan puertas traseras por ejemplo). Dicho esto la OnlyKey es la llave de seguridad más flexible del mercado hoy por hoy. Si tu principal preocupación es proteger tus claves privadas frente a un ataque de malware en el ordenador o un ataque hardware tipo BadUSB entonces OnlyKey es una buena opción.

### ⭐⭐⭐⭐⭐ Molto utile, ma decisamente non plug & play
*by S***I on 13 February 2020*

La prima cosa da dire, per evitare malintesi, è che si tratta di un dispositivo che non è assolutamente plug & play. Per utilizzarlo appieno e quindi apprezzarne l'effettiva utilità è necessario avere buone conoscenze e manualità informatiche. In parole povere: è un dispositivo adatto ad un professionista o per uno smanettone, decisamente più difficoltoso altrimenti. La configurazione, specie le prime volte, è un po' macchinosa. In particolare, visto che i valori si possono scrivere ma non leggere, è consigliabile farsene una brutta copia su un file di testo per evitare di dover reinserire tutto daccapo a mano se si deve cambiare solo una virgola. Unico neo per esperti: è un peccato che il supporto PGP si limiti ad una WebApp e si appoggi troppo ed esclusivamente su Keybase.
