Adfree browsing for my Patreons. - How to do it?

On my website I have lots of free content and I use ads to have some revenue. I also have a few Patreon supporters.

I would like to allow my Patreon supporters to view the content on my website without and ads.

  • Is it possible to do it?
  • Is it possible to do it without a user system on my site?
  • Have you done it? How?
