I just learned that there are two features within Adobe Acrobat that limits access to a PDF file ... very cool stuff. A"> https://helpx.

Document open password

A Document Open password (also known as a user password) requires a user to type a password to open the PDF.

Permissions password

A permissions password (also known as a master password) requires a password to change permission settings. Using a permissions password, you can restrict printing, editing, and copying content in the PDF. Recipients don’t need a password to open the document in Reader or Acrobat. They do need a password to change the restrictions you've set.

If the PDF is secured with both types of passwords, it can be opened with either password. However, only the permissions password allows the user to change the restricted features. Because of the added security, setting both types of passwords is often beneficial.
