Many users asked to have password protection system so that they can restrict pdf files from all users except authorized one. We are working on developing a different way to restrict pdf files but until we release, here’s a simple way which you can use to restrict/password protect pdf files.

There are many websites where you can upload a pdf file and give a password to it. Here’s one I tried and worked great:
https://www.pdfprotect.net/

You can use this website to convert your pdf to password protected pdf, download the pdf and use that password protected pdf with PDF Viewer for WordPress.

So, now you have to give the password to user. right ?

Thats not a problem actually, The page from where you’re linking to pdf viewer, can be logged in user only. So, only logged in users will be able to see link and content in that page.

You can put the password just beside pdf file link.

So now, when an user clicks on the link, he will be redirected to viewer which will ask for password. The pdf file will be accessible once the user put correct password in the field.
