David demonstrates how to password protect a PDF file for free without using docHub. docHub Reader, the free version, does not allow setting a password. However, users can easily password protect PDF files with LibreOffice, a free suite similar to Microsoft Word. This ensures that only authorized individuals with the password can access the PDF file.
