Note: YubiKey Personalization Tool is no longer under active development. Consider using YubiKey Manager instead.
Use the YubiKey Personalization Tool to configure the two slots on your YubiKey on Microsoft Windows, macOS 10.12, and Linux operating systems. The tool uses a simple step-by-step approach to configuring YubiKeys and works with any YubiKey (except the Security Key). You can also use the tool to check the type and firmware of a YubiKey, or to perform batch programming of a large number of YubiKeys. In addition, you can use the extended settings to specify other features, such as to disable fast triggering, which prevents the accidental triggering of the nano-sized YubiKeys when only slot 1 is configured.
