Age Verification Popup Show Only Once BY Account instead of by Cookie Memory

Greeting,
I am doing an age verification popup targeted only to the landing page of login.

The show-only-once function was set but only for cookie memory of the browser. That is- if I login to the same account in other device or incognito/ inPrivate, it will show up anyway, and vise versa.

Here are the script code for the age verification. Not sure if there is options for account-based show-only-once.

jQuery(document).ready(function($){
 
if (sessionStorage.getItem('advertOnce') !== 'true') {
//sessionStorage.setItem('advertOnce','true');
 $('.box').show();
}else{
 $('.box').hide();
}
 
$('#refresh-page').on('click',function(){
$('.box').hide();
sessionStorage.setItem('advertOnce','true');
});
 
$('#reset-session').on('click',function(){
$('.box').show();
sessionStorage.setItem('advertOnce','');
});
 
if (sessionStorage.getItem('advertOnce') !== 'true') {
//sessionStorage.setItem('advertOnce','true');
 $('.overlay-verify ').show();
}else{
 $('.overlay-verify ').hide();
}
 
$('#refresh-page').on('click',function(){
$('.overlay-verify ').hide();
sessionStorage.setItem('advertOnce','true');
});
 
$('#reset-session').on('click',function(){
$('.overlay-verify ').show();
sessionStorage.setItem('advertOnce','');
});
 
 
});

Many thanks
