PDF Password Secrets

A protected PDF Document may have 2 kind of Passwords. User Password & Owner Password.

User Password: It is also called as Document Open Password. It is required to open the protected or secure PDF file.

Owner Password: Owner password is protect the restrictions imposed on the PDF file. Owner of PDF file may impose restrictions such as Copying, Printing, Signing, Editing etc. These restrictions are protected with so called Owner Password so that no one else can change it.

Generally you can protect your sensitive PDF files with normal password (user/document open password).

However if you want to set advanced restrictions such as copying/printing etc then you also need to set 'Owner Password' (also caleld Permissions Password) to prevent anyone removing these restrictions. You can easily set these restrictions along with password using 'Advanced Settings' dialog in PDF Password Protector.
