The ykinfo command is a command-line tool used to retrieve information from and configure YubiKey devices. It allows users to query the device's version, serial number, supported capabilities, and other relevant metadata. It's particularly useful for scripting and automation, enabling system administrators to easily manage and monitor YubiKeys deployed across an organization. Furthermore, it is used to read all available data from a YubiKey including OTP, version, mode, etc. It supports several options to enable specific output formats and to query/program specific features of the YubiKey. Using this tool requires an understanding of YubiKey configuration and usage, as some commands can potentially alter the device's behavior. This tool is crucial in environments where YubiKeys are used for authentication, access control, or secure storage.

Some options require specific permissions or device drivers to be installed.
Alway test setting on a non-production environment first.

ykinfo exits with status 0 if the operation was successful and 1 if not.
