I have a page built which needs to have a password protected area added on it. In other words, when a visitor comes to the site and purchases a product they will be directed to a thank you page which will send them an email with an password and a URL. They will then visit this URL and must provide a password to be able to access their e-deliverable product. The page is built in Word Press. I need this done immediate. My budget is puny. Please help.
