selling digital magazines via login or download?
Hello,
If you want to sell your digital published content online, would it be possible to make the InDesign online publishing page a login member page, where members get to login and read the magazine?
How is this done these days?

Say I have created a landing page to sell a digital content magazine. The customer pays via the checkout cart on the landing page, they then receive an email with a link to view the digital content. How would I make that content a member only login or login and download? Assume I would embed that ebook/magazine on my own site with a login there?
What if the document is interactive with custom fill in areas like a workbook and I want each member to have their own version of the ebook to fill in with their own writing? Is this the way to go with this? Or should I approach that with adobe XD ?
kind regards,
