Class BasicAuthenticate

Basic Authentication adapter for AuthComponent.

Provides Basic HTTP authentication support for AuthComponent. Basic Auth will authenticate users against the configured userModel and verify the username and passwords match.

Using Basic auth

Load AuthComponent in your controller's initialize() and add 'Basic' in 'authenticate' key

 $this->loadComponent('Auth', [
     'authenticate' => ['Basic']
     'storage' => 'Memory',
     'unauthorizedRedirect' => false,
 ]);

You should set storage to Memory to prevent CakePHP from sending a session cookie to the client.

You should set unauthorizedRedirect to false. This causes AuthComponent to throw a ForbiddenException exception instead of redirecting to another page.

Since HTTP Basic Authentication is stateless you don't need call setUser() in your controller. The user credentials will be checked on each request. If valid credentials are not provided, required authentication headers will be sent by this authentication provider which triggers the login dialog in the browser/client.

Namespace: Cake\Auth
See: https://book.cakephp.org/3/en/controllers/components/authentication.html
