Yubico has decommissioned the Yubikey Personalization Tool previously used for configuring YubiKeys for OTP (One-Time Passcodes) that is used for Mason’s Duo configuration. These instructions are for how to use the replacement tool, YubiKey Manager to configure the YubiKey.
Help and tips if there are issues using the tool such as ensuring you allow the tool access to your machine for configuration are available via YubiKey Troubleshooting from Yubico.
