Newbie Timeout Feature
You can set the Timeout feature of Newbie so that after the designated number of minutes of no activity (mouse or keyboard movement), Newbie will lock itself and require the user to enter the password. This will prevent others from accessing your online accounts while you are away from your computer.
To set the Timeout feature, click User menu->Change User Info:

Set "Timeout (Mins.)" to the number of minutes before Newbie Timeout takes effect when no user activity occurs. You can disable this feature by setting it to 0. If you'd like to terminate Newbie instead of displaying the password verification screen shown below, check the "Terminate Newbie on Timeout" option.
