Once you are on my website you can log in using your Patreon account after that you can access all posts. If you have set your Patreon to expire you will automaticly lose access to the posts on my website at the end of the month.
The only thing being stored in the website is your e-mail so your password isn't being stored. You are logging in through Patreon on the website that's how it works.The plugin i am using is made by Patreon. I've added a second image to this post that shows you what you allow to when you log in. The website is also running SSL which means all data is being encrypted.
