How do I add a password to a PDF?

Set a password for the file on the Protect PDF page, then share that password with recipients separately from the document.

What encryption does password protection use?

It uses real AES-256 encryption, so the protection holds up even if the file ends up somewhere it shouldn't.

Yes — use Unlock PDF with the same password to remove the protection whenever it is no longer needed.
