Acrobat has various in-built security features controlling access to PDF documents. Within Acrobat these features have to be set on a file-by-file basis (by selecting the File > Save As menu item).Mapsoft SecuritySetter allows you to set these security features.Using the SecuritySetter tool you can set two types of password to limit access to your PDF files. 1. Open the Document password Users must enter this password, sometimes referred to as the user password, before they can open the document to which it applies. 2. Change Security Options password Users must enter this password, sometimes referred to as either the master or owner password, if existing security options are to be changed. It is advisable to set this password, as if it is not set, anyone who opens the file could then remove any restrictions that might apply to it. Passwords can be changed or deleted. However, passwords cannot be recovered from the document should you forget them.
