OTP test

Can be performed without any install as OTP is using the keyboard emulation mode.
As an HID device (keyboard), the YubiKey actually emits "scan codes" rather than actual characters. Different keyboard layouts have a different mapping between scan codes and the characters they represent.
Therefore, Yubico has designed a character set which is invariant between keyboard layouts which has 16 characters and we call the Modhex set – Modified Hexadecimal. Therefore, each character has 4 bits of entropy. 

Parameters
device=neonano
key=ccccccdugjdbtnglkbibhjkeifunghgngibgfjcunlfl
identity=ccccccdugjdb
serial=3037217

Install

For CCID & U2F, one needs some extra steps.
Note that contrary to what is said in Yubico docs, mine had already the mode U2F activated.

To use U2F with Chrome, install FIDO U2F plugin

We need the yubikey neo manager, cf NEO-Manager-Quick-Start-Guide.pdf Install Yubikey neo manager, here yubikey-neo-manager-1.1.0.tar.gz 

sudo apt-get install ykneomgr python-pyside yubikey-personalization yubikey-personalization-gui u2f-host
tar yubikey-neo-manager-1.1.0.tar.gz
cd yubikey-neo-manager-1.1.0/scripts
./neoman

Serial: 3037217
FW version: 3.3.0
U2F/FIDO: supported
Change connection mode [OTP+U2F]

We can change its name for sth more convivial
There are three supportes that can be activated:

  • The OTP mode refers to the YubiKey functions the NEO shares with the standard YubiKey, including two Configuration Slots that can be programmed with any two of the following: Yubico OTP (programmed by Yubico in Slot 1, by default), OATH-HOTP, Challenge-Response and Static Password.
  • The CCID Mode refers to the smart card elements on the YubiKey NEO and NEO-n, and includes the NEO applets such as OpenPGP, PIV and YubiOATH.
  • The U2F Mode refers to the Universal 2nd Factor (U2F) functionality of the YubiKey NEO and NEO-n.

Activate all supports:

  • Change connection mode => +OTP +CCID +U2F
  • unplug/wait/replug

Now we see available applets

  • YubiKey OTP
  • YubiOATH
  • Yubico U2F
  • OpenPGP
  • Yubico PIV
