Kon-Boot is an application which will silently bypass the authentication process of Windows / OSX based operating systems. Kon-Boot modifies the system kernel while it boots, changes are made temporary only. Rebooting the machine will restore the original contents of system kernel and its corresponding authentication procedures.
