This plugin sets user cookie when user is logged in. 
You can use cookie as data store, 
so you can use it as UI resource.
<h4>Visibility</h4>
This plugin adds class to <code>html</code> element.
<ul>
<li><code>ct-logged-in</code> The current user is logged in.</li>
<li><code>ct-not-logged-in</code> The current user is anonymous.</li>
</ul>
You can control elements visibility with CSS.
<pre>.some-element{
 display: none;
}
.ct-logged-in .some-element{
 display: block;
}</pre>
<h4>From JavaScript</h4>
You can use Global Object <code>CookieTasting</code> for utility.
<ul>
<li><code>CookieTasting.userName()</code> Returns user name. If not logged in, returns ‘Guest’.</li>
<li><code>CookieTasting.lastUpdated()</code> Returns timestamp of last log in check. If this equals 0, it means that user is anonymous.</li>
</ul>
Besides that, this plugin checks periodically log-in status. 
You can handle it with jQuery.
<pre>jQuery( document ).on( 'cookie.tasting', function( event, response ) {
 if ( response.login ) {
 // User is logged in.
 // If you use React...
 setAttributes({ name: CookieTasting.userName() })
 } else {
 // User is not logged in.
 }
} );</pre>
If you use react or something, updated the status with <code>setState()</code>.
<h4>Check Before Action</h4>
If you manage cached WordPress and customizing your own theme, 
It’s a good idea to implement dynamic UI components with JavaScript.
You can check user’s credential just before important actions.
<pre>// Click action for button.
$('.read-more').click( function( e ) {
 e.preventDefault();
 // Check cookie before do something.
 CookieTasting.testBefore().then( function( response ) {
 // Now user has fresh information.
 // Load premium contents.
 loadPremiumContents();
 }).catch( function( response ) {
 // This user is not logged in.
 // Redirect them to login page.
 window.locaion.href = '/wp-login.php';
 } );
} );</pre>
Plese remember adding dependency for <code>cookie-tasting-heartbeat</code> to your script.
<h4>Handle UUID</h4>
By default, this plugin set UUID for each user. This will be…
<ul>
<li>Unique for each logged in user and will be saved as user_meta.</li>
<li>Also kept for anonymous user.</li>
</ul>
So you can use it for Google Analytic’s <a href="https://support.google.com/analytics/answer/3123662" rel="nofollow ugc">User ID View</a>.
<pre>const uuid = CookieTasting.get( 'uuid' );
// For Google Analytics.
ga( 'set', "userId", uid );</pre>

Cookie Tasting

nice idea !!!

Detect user login only with cookie. The best helper for cached WordPress sites.

Cookie Script

CookieScript helps your WordPress site meet privacy requirements like GDPR, CPRA, PIPEDA and more. It adds a cookie banner to your site—no need to edit files or write any code yourself.
You can use it right after installing, even without a CookieScript account. Later on, if you want to adjust how the banner looks or behaves, you can link an account to unlock more options.
The plugin works with Google Consent Mode v2 and the WP Consent API, and can block third-party cookies until a visitor gives permission. It keeps your site compliant without interfering with tools like Google Analytics or ads.
