It is possible to limit the access to a PDF file and securing it by setting a password or by using certain restricting features i.e. printing, copying and editing. Here are the two types of passwords used to secure PDF files:

Document open password

The document open password is also known as “User password” and it requires the user to enter the password in order to unlock the PDF and view its content.

Permissions password

A permission password is also known as “Owner password”. You can restrict the printing, editing and copying of content in the PDF file by using the permissions password. The document can be opened in Adobe Reader or Acrobat without a password, but it needs the password in order to change the restrictions of copying, editing or printing.
