Smart Card on iOS

The Smart Card on iOS feature within Yubico Authenticator for iOS allows you to provision the public portion of a smart card certificate stored on your YubiKey to the iOS Keychain on your device. Once provisioned, you can use the Yubico Authenticator app together with your YubiKey to perform TLS authentication within the Safari browser and to sign and decrypt emails via S/MIME in supported mail clients on iOS and iPadOS devices.
