Reboot and when the Grub menu appears, select Recovery/Single User and
it will take you to a root mode that you can use to passwd your user and
change the password.  If you don't have that option you can edit the
Kernel options and put:

'single rw init=/bin/bash' and then it will boot into single user mode.
