I just got my Yubikey Neo with U2F support and I felt like the documentation on how to get it up and running was a bit hard to find. If you are having trouble getting started with U2F these few quick steps will help you get through it.
Step 0: Download and install the Yubikey Neo Manager application. This is NOT the Yubikey Personalization Tool! The Yubikey Personalization Tool does not support enabling U2F yet.
Step 1: Open the Yubikey Neo Manager with your Yubikey installed and click Change connection mode [OTP]
Step 2: On the Change connection mode
check the U2F
box to change the setting from OTP
to U2F
and click OK
.
The application will now prompt you to remove your device. You can remove it and plug it back in again. Close the Yubikey Neo Manager application.
Step 3: Open Chrome and install the FIDO U2F (Universal 2nd Factor) extension from the Chrome web store.
Step 4: Register on Yubico’s U2F demo page and you’re done.
Now you can log in on the demo page and other sites that support U2F.
