Until everything is USB-C, having both A and C and NFC all in one durable metal package is a no-brainer. Most of the other brands aren't that flexible and look cheaply made.

This key is value for money when you compare it to other brands it is accepted by almost all sites that another brand can. iIt's easy to register, and easy to set up on the sites where you would like extra security. I am very happy with this purchase, and I think you will be as well.

La combinaison de l'USB A, USB C et NFC est idéale. Ayant cassé un précédent petit dongle USB A FIDO2 en le laissant connecté sur le PC portable (bien qu'il ne dépassait que de moins d'un cm), je voulais quelque chose de plus solide. Là, c'est livré avec un petit étui et je ne le laisserais plus en permanence sur le pc.

It really makes using a password manager a joyful experience almost as easy as the face recognition on my iPad.

Ich habe den Key gekauft, um die Funktionen des neuen FIDO2 Systems zu testen. Der Key funktionierte nach Konfiguration des Systems auf Anhieb und 100% zuverlässig. Keine Cloud-Verbindung, keine Komplexität in der Benutzung. Damit erfüllt er die wichtigste Voraussetzung neben der an sich sicheren Authentifizierung: zuverlässig und offline nutzbar. Ich habe den Key auf einem Linux-Notebook konfiguriert.

I’m not an expert on security keys but I preferred this one since it’s the cheapest available key and you can connect to almost any device with USB-A, UAB-C and NFC. I tried all connection types and they all worked well.

Funktioniert einfach und zuverlässing mit den gängigen Browsern (Edge, Chrome) unter Windows und Android. Unix/Linux habe ich nicht getestet. Am meinem Mobiltelefon mit Android 13 auch mit USB und NFC. Nun kann ich meinen FIDO2 Key am PC und auch modil verwenden. So soll es sein.
