When sending out PDF documents to others, it's often a good idea to apply copy protection and other document restrictions, such as printing and editing. This will prevent unauthorised users from copying the PDF content. To properly change any restrictions, you must enter the document's permissions password in Adobe Acrobat. The permissions password is created by the PDF author in the security settings of Adobe Acrobat.
