You can change your password anytime from the Control Panel. This is the only place from which you can change your password.
Simply click the menu item “Change Password” then “Change IMLlock Password” and a change password screen will appear. You must type the old password (the password you wish to change) then the new password. Then re-type the new password in the third box.
You will receive a messagebox when the password is successfully changed.
Remember to store your password in a safe place, as this password will allow anyone to access your Administrative Control Panel.
