Setting a Password

You can set a password on a PDF document so that only users who know the password will be able to open the document.

To save a PDF file with a password, click Save PDF in the File group on the Home tab. A new window will open. Select a new name for the document. Next, click the Security tab on the right-hand side of the Save As window. Select the Require a password to open the document check box, and enter the password.

Click Save.
