Qt based Cross-Platform YubiKey Personalization Tool

This project is no longer under active development. Use YubiKey Manager (GUI, CLI) to configure a YubiKey device.


The YubiKey Personalization Tool is a Qt based Cross-Platform utility designed to facilitate re-configuration of YubiKeys on Windows, Linux and Mac platforms. The tool provides a same simple step-by-step approach to make configuration of YubiKeys easy to follow and understand, while still being powerful enough to exploit all functionality both of the YubiKey 1 and YubiKey 2 generation of keys. The tool provides the same functionality and user interface on Windows, Linux and Mac platforms.

The Cross-Platform YubiKey Personalization Tool provides the following main functions:

  • Programming the YubiKey in "Yubico OTP" mode

  • Programming the YubiKey in "OATH-HOTP" mode

  • Programming the YubiKey in "Static Password" mode

  • Programming the YubiKey in "Challenge-Response" mode

  • Programming the NDEF feature of the YubiKey NEO

  • Testing the challenge-response functionality of a YubiKey

  • Deleting the configuration of a YubiKey

  • Checking type and firmware version of the YubiKey

Building from Git

You may check out the sources using Git with the following command:

  $ git clone

This will create a directory yubikey-personalization-gui. Enter the directory:

  $ cd yubikey-personalization-gui


yubikey-personalization-gui depends on version 1.14.0 or higher of libykpers.

When building on Windows and mac you will need a binary build of yubikey-personalization, the contents should then be places in libs/win32, libs/win64 and libs/macx respectively.

For building on linux pkg-config is used to find these dependencies.

On Debian-based systems (Ubuntu, Linux Mint, etc.):

  $ sudo apt install libusb-1.0-0-dev qt4-qmake libykpers-1-dev \
      libyubikey-dev libqt4-dev

On Fedora-based systems (RHEL, CentOS, Scientific Linux, etc.):

  $ sudo dnf install libusb-devel qt-devel ykpers-devel libyubikey-devel

Command-line build

Run these commands:

On Debian-based systems:

  $ qmake && make

On Fedora-based systems:

  $ qmake-qt4 && make

Cross Compiling from Linux

The project can be cross compiled from linux for OS X and Windows. As a first step you need a cross-compiler chain for that OS, for windows you want mingw-w64.

Then you need unpacked Qt binaries for that platform.

You can then do (for Windows): TARGET_ARCH=i686-w64-mingw32 QTDIR=<qt location> qmake \ -spec win32-g+-4.6 "CONFIG=cross"

To build installers you can add build_installer to the CONFIG variable for qmake. This requires makensis to be in path for windows and genisoimage and dmg (from libhfs-dmg) for Mac.

Opening the project in Qt designer

Locate the qtcreator executable file and click on it to open the Qt Designer.

To open the project in Qt Designer, select File > Open File or Project from the tool bar, navigate to the project folder, select file and click on the Open button.

To set the path of the Build diractory select Projects > Build Settings Browse project folder path.


To generate the build system, select Build > "Clean Project YKPersonalization" option from the tool bar. Then select Build > Run qmake option from the tool bar.

To build the project, select Build > Build Project YKPersonalization option from the tool bar.

Based on your platform, the successful build will create a YubiKey Personalization Tool executable file into the respective build folder. The build creates a YKPersonalization.exe file on Windows, YubiKey Personalization file on Linux and YubiKey Personalization file on Mac.

Example on Linux: To run the YubiKey Personalization Tool, open the command shell and execute the following command:

  $ build/release/yubikey-personalization-gui
