Read our editorial standardsWhen to protect a PDF
Use password protection when sending sensitive PDFs by email, storing documents in shared folders, or giving temporary access to business documents. It is especially useful for files that include private or commercial information.
Choose a strong password
Avoid simple passwords based on company names, birthdays, or common words. Use a password that is difficult to guess and send it through a separate communication channel where possible.
Understand the limits
Password protection helps control casual access, but it does not replace full information security. For highly sensitive documents, use secure storage, careful access control, and proper internal policies.
