Until now, we have learned the different ways to call a Flow, and a Visualforce page is one of them. Once you have embedded Flow into a Visualforce page, business users can use it without having the Run Flow system permission or the Force.com Flow User feature license. In the beginning of this chapter, we had already discussed ways to embed a Flow into a Visualforce page.

In Chapter 2, Creating Flow through Point and Click, we created a Flow for survey purposes, Displaying feedback form based on age. Now we will open it for unauthenticated access using Force.com sites. This means that anyone can use this Flow to share their feedback without logging in to Salesforce.
