2. Create a Data Source which will fetch the above formula field. In this example, I have a custom object called Custom Invoice. On that object I have a lookup to Contact record. So Query the contact lookup formula field.

4. Now go to Custom Invoice record, add the Doc config to the pade and generate the PDF. As we enabled password protection, PDF Butler previewer will ask for the password. Also downloaded PDF will ask for password.
