Protect a PDF when controlled access to the document is required

PDF protection is intended to add access controls to a document you are authorized to secure. A strong password can help restrict casual access, but the password must be stored safely because losing it can also make your own document difficult to open.

Protection settings should match the way the file will be distributed. A document being emailed to another person has different requirements from a file kept only as a private archive.

Good protection practices

  • Use a strong, non-reused password for important files.
  • Share the password through an appropriate separate channel when needed.
  • Test the protected result once before deleting or archiving the source copy.

Before distribution

  • Confirm the PDF opens only with the intended credentials.
  • Do not assume password protection replaces proper handling of highly sensitive data.
  • Keep a secure original or recovery copy where appropriate.

Before relying on the result

Keep the source until you have checked the generated output. The source and destination formats can represent structure, layout and metadata differently, so important documents should be reviewed in the application or device where the result will actually be used.
