If you want to enable your end users to authenticate
using a smart card or common access card (CAC), you must import
the Root CA certificate that issued the certificates contained on
the CAC or smart cards onto the portal and gateway. You can then
create a certificate profile that includes that Root CA and apply
it to your portal and/or gateway configurations to enable use of
the smart card in the authentication process.
Two-factor authentication using smart cards is supported on macOS and Windows
endpoints.
