The Special Edition Octocat Key is a FIDO U2F Security Key, created for GitHub users. It is a U2F-only security key, meaning you cannot configure the key for any other use. Because you cannot configure this special key, this key is not recognized by the YubiKey Personalization tool.

Note, however, that you can use this U2F-certified key with other U2F services, such as Gmail, Google apps, and Dropbox. To see where else you can use your U2F-certified YubiKey, see our FIDO U2F page.
