I have Zorin 16 installed and I have forgotten my password. I am not sure what my User ID is either. When I start the PC, it asks for my login Password and then I am stuck. How can I reset my password? I wish you guys would have a more sophisticated security system. I don't use Grub, so the tip to drop down into the command line does not work for me.
Thanks in advance for your help!
When you get to login prompt, press Ctrl+ Alt+ F3 to bring up tty (terminal). To proceed in resetting forgotten password:
Thanks for your interest in my problem. I used Ctrl+Alt+F3 to start the terminal and the first thing it wanted was my user ID and password... 
Let me review my problem:
I do know my user ID (so that's good).
I don't seem to have Grub Installed (or running) so I can't get to the recovery menu.
The suggested video assumes that I can actually enter commands without the system requiring my password.
I am thinking I will reinstall Zorin and then restore the backup to get my files. Will that just put me back where I am now because it will overrwrite my security settings?
Yes, when you do a fresh install it is like painting on a blank canvas. Whenever I do a clean install I create a fresh partition table in GParted.
