How to make a lesson free in a free or paid course
If you do not want your students to sign in before watching some or all of your lessons, you can make the lessons free, even if the whole course is already free or paid.
To set up free lessons for your courses in OnlineCourseHost.com, log in to your account => click Products => Edit => click the Lesson in question => scroll down, and toggle the button to Free Lesson => then click Save to apply changes.

Please note that you can turn the free button on and off as you wish, as it is an optional tool. You can also select all the lessons in the course and make them all free.
