I log out of my Macbook then shut down. When I turn my Macbook back on there is no Log in. Anyone can now walk up to my Macbook and read anything on it.

I use this formula to reset Admin login password:

Resetting a user's password in OS X Lion and Mountain Lion

Important: Passwords for administrator accounts should not be blank.

1. Log in with an administrator account. Tip: If you don't know the password of any administrator accounts, see "Resetting the original administrator account password" below.
2. From the Apple menu choose System Preferences.
3. From the View menu choose Users & Groups.
4. Click the lock button if it appears locked; enter the administrator password.
5. Select the name of the user whose password you want to change.
6. Click the Reset Password button or the Change Password button.
7. Enter a new password in both the New Password and Verify fields, and add a Password Hint if desired.
8. Click the Reset Password button or the Change Password button.

And the change password has me making a new Apple ID. I don't need a new Apple ID. I need a new Admin login so that when I turn on my Macbook I need to login with a password before I can used the Macbook. Amd I asking the wrong question of support?
