How to organize access to paid materials on the site?

Question

HTML

Good afternoon! It is necessary to organize access to paid content on the site. Making a personal account with a login and password for everyone is long and dreary, so it’s not an option.
In addition, the following options come to mind:
1. Just set a password on the page that is the same for everyone. But there are a lot of minuses here: the password is easy to transfer to each other, and also some browsers incorrectly perceive the script and do not ask for a password, but immediately open access to the content.
2. The second thing that comes to mind is to request a person's email, check it against the email database of users who have paid, and if paid, redirect to the content page, and if NOT paid - to the payment page. Please tell me the script how to do it right
Or please suggest other options! Thank you in advance. The site is written in HTML and PHP
