I am adding metadata to my document:
\hypersetup{
pdftitle={ddd},
pdfsubject={aaa},
pdfauthor={xxx},
**pdfkeywords={666},**
pdfproducer={yyy!},
And there is a password string here, however the document does not ask for a password when opening it. How to password protect a document?
pdfkeywordsis for keywords, not passwords. – DG' Jun 16 '20 at 08:05
