Yubico Forum

Hi,
I just stumbled upon this and fixed my new YubiKey neo to work with WP8 and WP8.1. It all works on windows 8 perfectly without the need for linux. Oh and you don't need to keep m82 enabled. I switched back to m0 becasue I don't need smart card support right now and it works like a charm.
basically what I did is:

1. download an unpack ykpers-1.15.1 from http://yubico.github.io/yubikey-persona ... eases.html
2. opened command line interface with admin privileges
3. entered devmgmg.msc to make sure there is no other SmartCard device in my laptop
4. entered ykpersonalize -m82 and confirmed by y
5. unplugged and replugged the Yubkey NEO.
6. waited for windows to recognize the smart card interface and install the default drivers
7. downloaded and unpacked GPShell-1.4.4 from http://sourceforge.net/projects/globalp ... p/download
8. downloaded gp_wp8fix from download/file.php?id=24
9. entered gpshell gp_wp8fix in the command line interface
10. unplugged, tested on a WP8 and WP8.1 phone and replugged the Yubkey NEO
11. entered ykpersonalize -m0 and confirmed by y in the command line
12. done.

Oh but there is ONE glitch: the NFC seems to work only ONCE. After you used it, it gets ejected and you need to reconnect to a PC via USB again, otherwise the NDEF message is emtpy again. Really weird.
Does anyone else observe this behaviour? Is there any fix?

ah no, it seems to have nothing to do with the connection to a PC. It is somehow connected to the the touch button! But it's random. Sometimes the NDEF message is empty, sometimes it contains the required one-time-URL. What's to do?

Unfortunately, Nokia's and Microsoft's documentation is very limited with regards to NFC. The stack seems to be confused that we both support Type 2 (Mifare Classic) and ISO14443-4 so the fix changes the response to appear as a Mifare DESfire tag.

Unfortunately this is an hack to address lack of support from Windows Phone's API and the best you can do as a Windows Customer is to inform MS to update their APIs
