There are two levels of password protection that can be set – one for opening the PDF (also known as the document open password), and one for making changes or modifying the PDF (also called the permissions password).

Note

There is no way to recover a password from a PDF document. Store your passwords in a safe place, or keep a non-password protected copy of the file as back-up in case you forget the passwords.

Password Settings

If the document open password is set, anyone opening the PDF will have to type in the password you specify.

 

With the permission password (change document) set, this password is needed to change the security settings or to modify permissions on the document, such as whether content copying or form field editing is allowed.

 

If both passwords are set, either password will open the PDF file, but only the permissions password will allow you to change the permissions on the PDF.

You can only modify PDF security options if you have selected PDF as your file format. In all other cases, this screen is not applicable, and skipped.
