I do have a question and couldn't find the answer in current forum threads.
I want to restrict access to a page on my site. Only people who have received a unique (physical) code, should be able to view content on a page. Consumers shouldn't have to register or give more information (like email addresses, names, etc.), the code should be enough. There will be 5000 unique codes that give access to the content.
I have explored options like Sentry Login, but these tools all focus on registration and then grant access, instead of giving access via the codes.
I hope someone can help me to find a way to make this work.
Many thanks in advance!
