Initialize your Yubico token

To initialize your Yubico token, you need to set:

Note

For certificates enrolled on Yubico tokens, if your application is not displaying these certificates, try removing and reinserting the token.

Restrictions

  • Yubico tokens cannot import Certificate Authorities (CA) because each slot is limited to storing one certificate.

  • When a certificate is deleted from DigiCert​​®​​ Trust Assistant, the private key associated with the certificate will not be removed from the token. The same restriction applies when using YubiKey Manager.

  • When the Yubico token is used by the operating system or other third-party applications, it may lose connection with DigiCert​​®​​ Trust Assistant. Refer to the troubleshooting steps in the next section to resolve the issue.
