LearnDash Course Access Manager
LearnDash Course Access Manager gives you the ability to add basic access levels to your site, which is a great option if you don’t need all the features of a robust membership plugin. Charge a one-time fee or recurring payments, and auto-update a user’s access level after a set number of days. Note: LearnDash has a built-in content protection for your course content. The Course Access Manager plugin is not required in order to sell and protect your course content. It is completely optional.
