Is It Safe to Password-Protect a PDF File?
No, it’s not safe to password-protect PDF files because your files are not guaranteed to be protected from cybercriminals intercepting and gaining unauthorized access to your information. Often, people password-protect a PDF file to protect sensitive information and set permissions on how the PDF file can be used. If you password-protect a PDF file, you can choose whether you want a recipient of the file to view or edit the file.
