Not really sure where the best place was to post this, so hoping I've chosen the correct place. Our company are currently working towards PCI Compliance and one of the things we envisage coming in soon is the need for two factor authentication. The PCI Guidelines already require two factor authentication for external remote access, so its only a matter of time before this becomes the norm for internal access too. So, are there any apps that allow two factor authentication for OSX? Anyone used any and can share opinions?
