Placeholder copy — real how-to to be written later. Headings and steps are representative so the table of contents renders.

Putting a password on a PDF is the simplest way to keep it from the wrong eyes. Here are three approaches, from quick-and-local to fully shareable.

Option 1: lock it on your computer

Most operating systems can export a password-protected PDF directly.

On macOS

A few clicks in Preview will do it.

On Windows

Office apps can encrypt on export.

Instead of mailing a locked file, share a link that asks for a password and expires when you want.

You can revoke access, set an expiry, and see whether it was opened.

Option 3: combine both

Belt and suspenders for the most sensitive documents.

Which should you use

A quick rule of thumb based on how sensitive the document is and who needs it.
