You can also protect the information in the PDF documents you are creating by applying a password to the PDF file. If you want to be able to control who can open the PDF file and who is allowed to make changes to it, this is the approach to take.

There are two levels of password protection - at the document open level when the PDF file is opened in the viewer, and again when someone tries to modify, or change, the PDF.
