About PDF Password
There are two forms of password protection: User/Open Password and Owner Password. The user password defined by the people who create the PDF file is used for preventing unauthorized access. Only those people who know the password can open the user password protected PDF files. An owner password lets you block access to document features, including printing, editing, and commenting, as well as copying, extracting, or modifying content. In addition, with the owner password, you can control whether users can fill in form fields and sign existing signature fields.
