What is the difference between courses and memberships in terms of protecting content?

LifterLMS courses automatically protect lessons.

LifterLMS memberships can be used for the following purposes:

• To sell bundles of courses
• To offer a course or courses PLUS non LMS content like other posts, pages, or parts of pages, and even access to other benefits
• To offer access to non LMS content like other posts, pages, or parts of pages, and even access to other benefits
• Only allow access to the entire site to users with a specific membership level

LifterLMS courses and memberships are sold or allow enrollment (if free) via access plans.
