Hi lindseyk78117521 ,
Would like to inform that you may able to secure the PDF Files with the passwords using Acrobat Pro DC program .
Refer to this KB article :- https://helpx.adobe.com/acrobat/using/securing-pdfs-passwords.html
Let me know if it works.
Possible with Acrobat Standard and Acrobat Pro.
Are these versions of Adobe free?
These versions are not free.
So the only way I can secure a PDF with a password is to buy one of these versions of Adobe? There is not a free option?
Adobe offers no free option.
