YubiKey Manager

Cross-platform application for configuring any YubiKey over all USB interfaces.

Note	This project is no longer under active development. We recommend Yubico Authenticator to configure a YubiKey.

This application provides an easy way to perform the most common configuration tasks on a YubiKey.

The current version can:

Display the serial number and firmware version of a YubiKey
Configure a FIDO2 PIN
Reset the FIDO Applications
Configure the OTP Application. A YubiKey have two slots (Short Touch and Long Touch), which may both be configured for different functionality. This tool can configure a Yubico OTP credential, a static password, a challenge-response credential or an OATH HOTP credential in both of these slots.
Manage certificates and PINs for the PIV Application
Swap the credentials between two configured slots
Enable and disable USB and NFC interfaces

Installers are available here.

In addition to the application itself, you may also need to manually install and start the pcscd service for CCID support.

AppImage is available here.

To install from source, see the development instructions.

This project also bundles the command line version.
