Hi
You can do away with the password by doing this...
Open the Run Window.
Type netplwiz
Uncheck the box that says "User must enter a password to login" or something to that effect and click Apply.
If you have 2 users you may have to do that for both of them.
Both should show in the netplwiz window.
You should have the option to turn off the touch pad in Mouse & Touchpad settings.
Open Settings from the start button, and then type in Mouse and Touchpad Settings in the search window.
