The PDF document User- and Owner-Password

The standard security provided by Acobat PDF documents consists of two different passwords:

The "Owner"-Password (permission Password) allows to prevent PDF files from printing, editing (changing), selecting text and graphics, or adding/changing annotations and form fields.

The "User"-Password locks the document so the password is required to open and view the file.

If only the "Owner"-password is set, decryption is being done instantly, the decrypted file can be opened in any PDF viewer (e.g. Adobe Acrobat Reader). But the applied document restrictions can not be changed without the Owner Password.

When should you use this PDF Encryption Setting?
