Confirm password
Write it down first. The password never leaves your browser, so QuillPDF cannot recover it or reset it for you.
Restrictions
Restrictions are enforced by the reader, not the encryption. Treat them as a clear instruction, not a guarantee — the password is the part that actually protects the file.
