Protection is useful, not magic
PDF password protection helps prevent casual opening of the file. It is not a replacement for careful sharing, secure email practices or choosing the right recipient.
For sensitive files, send the password separately from the PDF. Do not place the password in the same message as the attachment.
What to check before sending
Make sure the protected output opens with the correct password and does not open without it. Also confirm the recipient knows how they will receive the password.
Open PDF security tools
Protect PDFs with real encryption or unlock files when you know the password.
