Yubico’s ykman is a cross-platform application for managing and configuring YubiKeys. It has a command line interface (CLI) that uses a Python 3.6 (or later) library.The YubiKey Manager is also a cross-platform application for managing and configuring a YubiKey via a graphical user interface (GUI). However, unlike ykman, the YubiKey Manager (GUI) cannot handle all the newest YubiKey firmware features. It is limited in scope. Therefore we recommend using Yubico Authenticator which supersedes the YubiKey Manager (GUI).The Yubico Authenticator, the YubiKey Manager and ykman all provide an easy way to perform the most common configuration tasks on a YubiKey, such as:Displaying the serial number and firmware version of a YubiKey.

These tools can configure:a Yubico OTP credentiala static passworda challenge-response credential oran OATH HOTP credential in either or both of these slots.Managing certificates and PINs for the PIV applicationSwapping the credentials between two configured slotsEnabling and disabling USB and NFC interfaces.ImportantThe installer for the YubiKey Manager GUI bundles together the GUI with an older version of the ykman CLI. The ykman CLI that is bundled with the YubiKey Manager GUI is not the most recent version.To use the ykman CLI, install the latest version found at Releases.
