Hi Folks,
I also have the Nokia 820 and I have run into the same problem.
Using the instructions above, I've solved the issue - but it gave me a major headache , because the instructions a a bit cryptic (which is understandable given the fact that we're talking cyptography
So here's my guide what to do:
UWE'S GUIDE HOW TO ENABLE YOUBIKEY NEO WITH WINDOWS PHONE 8 USING WINDOWS 8 OR 7
FIRST STEP: SET NDEF STRING
(taken form youbikey Website: https://helpdesk.lastpass.com/security-options/multifactor-authentication-options/yubikey-authentication/#YubiKey+NEO+with+Windows+Phone+8+App)
1. After you've registered the YubiKey with your LastPass account, ensure that mobile access is "disallowed" in your LastPass Icon > My LastPass Vault > Account Settings link > YubiKey tab.
2. Then download the Personalization Tool from Yubico at http://www.yubico.com/personalization-tool
3. In the Personalization tool, select the "Tools" option from the menu at the top
4. In the Tools menu, select the NDEF Programming Option
5. In the NDEF Programming option page, select Configuration Slot 1. Set the NDEF Type to "URI (http://..)", then in the NDEF payload field, type: "https://lastpass.com/mobile/?otp="
6. Press the Program button to write the NDEF2 string to your YubiKey NEO
SECOND STEP: SET YOUBIKEY TO SMARTCARD AND OTP MODE (MODE 82)
1. Download the ykpersonalize tool at http://yubico.github.io/yubikey-personalization/releases.html
2. Unzip it to your hard drive
3. Execute "[path]/bin/ykpersonalize -m82" (where [path] is the path to which you unzipped the tool)
4. Unplug the yubikey NEO
6. Reinsert the yubikey NEO
7. Verify that "Microsoft Usbccid (WUDF)" appears as a device in the smart Card section of device Manager
THIRD STEP: APPLY THE FIX
1. Download the WP8 fix at http://forum.yubico.com/download/file.php?id=24 (see post above)

3. Download to GPShell tool at http://sourceforge.net/projects/globalplatform/files/
