you can retrieve your password by unlocking the root user ... for this, you have to enter in recovery mode and then reset the root password

For entering in rescue mode

1.restart your computer

  1. press shift or Esc what is work for you ...

  2. Then choose an advance option

4.then use down arrow key for selecting root option

Now you can see root shell fire command

root@ubuntu: mount -o remount,rw /

after that change roots' password root@ubuntu: passwd [New Password] retype password

Now you can also change your administrative password by firing a few commands or you can login into root in GUI mode and then change it.
