Installation

YubiKey Manager can be installed independently of platform by using pip (or equivalent):

pip install --user yubikey-manager

On Linux platforms you will need pcscd installed and running to be able to communicate with a YubiKey over the SmartCard interface. Additionally, you may need to set permissions for your user to access YubiKeys via the HID interfaces. More information available here.

Some of the libraries used by yubikey-manager have C-extensions, and may require additional dependencies to build, such as swig and potentially PCSC lite.

Pre-build packages

Pre-built packages specific to your platform may be available from Yubico or third parties. Please refer to your platforms native package manager for detailed instructions on how to install, if available.

Windows

The command line tool ykman.exe is provided as part of the installer for the YubiKey Manager on Windows.

MacOS

Packages for MacOS are available from Homebrew and MacPorts.

Linux

Packages are available for several Linux distributions by third party package maintainers. Yubico also provides packages for Ubuntu in the yubico/stable PPA (for amd64 ONLY, other architectures such as arm should use the general pip instructions above instead):

sudo apt-add-repository ppa:yubico/stable
sudo apt update
sudo apt install yubikey-manager

Source

To install from source, see the development instructions.

Bash completion

Experimental Bash completion for the command line tool is available, but not enabled by default. To enable it, run this command once:

source <(_YKMAN_COMPLETE=source ykman | sudo tee /etc/bash_completion.d/ykman)
