YubiKey C Client Library (libykclient) is a C library used to validate a one-time-password (OTP) YubiKey against Yubico’s servers. See the Yubico website for more information about Yubico and the YubiKey.


Install the latest version of ykclient as follows:

Or install a particular version:

You can also install packages in augmented, pure or containerized environments for development or simply to try them out without polluting your user profile. See the guix shell documentation for more information.
