I would like to use Sign In with Apple JS on my website to show some pages or content only to predefined user. This is an example logic I would like to achieve:
if userID or userEmail == "someValue" { // show page or content }
In particular, I would like to show an admin panel only to users with particular username or email address or some ID or whatever.
I don't want to allow signing up with SIWA for anyone. And just use SIWA JS to allow a safe way of signing in.
Is it possible with Sign In with Apple JS?
P.s. Technology I would like to use on my website: HTML, CSS, PHP, JS.
