Review: muy buen producto, llego perfecto todo bien funcionan perfecto
Review: As with all things in security, what works in one environment may not work in another. This key works fine for web-based authentication. It doesn't do so well for OTP. To be more specific: it doesn't give you the information that you need in order to add it as a "hardware token" in Duo. It can be added as a WebAuthn token, but not as a HOTP token in Duo. So I can use it to login to web-based applications, but I can use it for my work VPN (which is not a web-based login). It works fine as a Google passkey, and it has worked for everything else I've tried it on the web.

I thought that this key was to authorize me to sign in before I could on line but not the case. Either iam doing something wrong or I got the wrong key!
