Work uses Two Factor Authentication using certificates. Presently they are on a USB smart card or a device with a smart card reader. So far it works well on Surface and Android tablets.  Did anybody see the iOS9 section if they will support certificates?   Living in a smartcard world, this is also a must. Apple hasn&#x27;t cracked the Citrix world so far, they keep saying iOSx+1.
