Customer Ratings & Reviews

The Yubikey 5C NFC is the latest version of the security key, featuring multiple security protocols, a touch interface, and NFC support. The setup process, as outlined by Yubico, is moderately challenging, requiring a step-by-step approach. Users must download either the Yubico Authenticator or Yubico Manager, each with distinct functionalities. For Yubico Manager, once installed, plug in the Yubikey to see the firmware and serial numbers. The simple interface has tabs for home, applications, and interface. It displays key information and supports OTP, FIDO2, and PIV protocols for both USB and NFC. The first crucial step is to set up a PIN for authentication by changing the default PIN in the applications tab. The Yubico Authenticator offers more features, including tabs for home, accounts, passkeys, and certificates. It provides additional details, like the number of accounts and passkeys stored, accessible via a PIN. This ensures unauthorized users cannot access the key's information without the PIN. If the key is lost, the Manager allows deletion of the key from your account, though you lose stored keys and OTPs. Yubico recommends having a backup key set up simultaneously and stored safely. Setting up two-factor authentication with the Yubikey is service-dependent. For Google and Microsoft accounts, enable two-factor authentication first, then add the security key via the Authenticator app on your phone. Simply touch the key to register it. Logging in thereafter requires the hardware key and PIN. Overall, the Yubikey 5C NFC provides superior security compared to app-based or OTP methods, ensuring control even without network access. The Yubikey authenticator offers additional support if the physical key is unavailable. The device works reliably, providing robust two-factor authentication, making it highly satisfactory.

Unboxing this there was no documentation. I tried to enroll this via the online video on yubico’s website and that option was not there. Ultimately I needed to download a Yubikey manager and click on slot 1 to get a serial, private and secret key. The. i needed to provide my companies admin to add to our Duo account. Then they added it for me. When I authenticated it was plugged into my computers usb-c port and nothing happened. Then I thru trial and error learned that I had to hold the gold circle down for 2-3 seconds to authenticate. I can see the value of this device but it is way too complicated for setup and from the online instructions I found to setup to authenticate to my Iphone it requires 2 keys not 1. This would only be something useful if you had it or Geek Squad to setup for you. They should provide better instructions or an app with guided setup. I think this would be scary if you did not have help setting this up in thinking that you can lock yourself out of your device or computer if done incorrect.

Excellent product. Although I had some trouble figuring out how it works at first, since it requires special software to set it up, I was eventually able to do it.

Awful, and terrible service, It was schedule to be delivered in 2 days but never arrived from OnTrack. Still waiting for my refund.
