I tried a lot to solve the authentication in Cake PHP 4, but I couldn’t even when the page link to login template  
I try to see it in the browser, it gives the following error, both Application.php is set and app.php, I also checked autoload in composer.json with GPT chat, but finally it doesn’t give the following error. I know what to do:

**# No authenticators loaded. You need to load at least one authenticator.📋**

RuntimeException

Have you tried following my workshop?

It seems you missed the `getAuthenticationService` part of [Quick Start - 2.x](https://book.cakephp.org/authentication/2/en/index.html#getting-started)
