I want to set a different password for each page that the user accesses and put restrictions on browsing.

On sites accessed by unspecified users, We would like to issue a different password for each page so that only users who know the password can access it.

Instead of basic authentication or httaccess, we expect the password to be pulled over mysql.

It looks like an article-specific password for wordpress, but
What kind of theory is generally used to apply password authentication to each page?
Is it like putting a unique value for each page in the session information during password authentication and confirming it one after another?
I would appreciate it if you could let me know.
