## What it is
A Python library and command line tool (ykman) for configuring YubiKey hardware security keys over all USB interfaces. It supports managing the OTP, FIDO2/WebAuthn, OpenPGP, PIV, and OATH applications on connected YubiKeys.

## Use cases
- configure a yubikey from the command line
- enable or disable applications on a yubikey
- manage PIV certificates on a yubikey
- set up OATH accounts on a yubikey
- list connected yubikeys and show device info
- script yubikey configuration with a python library
- manage openpgp keys on a yubikey

## When to choose
- you need to configure or manage YubiKey applications from a terminal or script
- you want a supported, official Yubico tool with a Python API for automation
- you need cross-platform YubiKey management without a GUI

## When to avoid
- you prefer a graphical interface (use Yubico Authenticator instead)
- you need to manage other brands of security keys
- you only need to generate one-time codes rather than configure the key
