The YubiKey FIPS token shipped with your EV Code Signing or Business Identity certificate will have its PIN blocked after three unsuccessful attempts to enter it. When the PIN is blocked, it is impossible to use your YubiKey to sign code or document files. If this has happened to you, here’s how to reset the PIN and start over.

  1. Download and Install YubiKey Manager.

    YubiKey Manager is Yubico’s configuration tool for Windows, macOS, and Linux. Navigate to the YubiKey Manager download page, download the installer for your OS, and install the software.
