Authentication

The new authentication plugin cakephp/authentication offers an improved way to handle authentication, we have created some additional features to enable:

• social auth;
• reCaptcha in form;
• cookie login with session;
• two-factor (one-time password) authentication

Custom Authenticators

• CookieAuthenticator, preserve cookie auth token at session, needed for login that perform redirect like in social authentication.

• FormAuthenticator, allows to use reCaptcha verification in your login form. Configurations:

  • keyCheckEnabledRecaptcha, config key used to check if reCaptcha is enabled. Default, 'Users.reCaptcha.login'
  • baseClassName, optional fullname class for base form authenticator

• SocialAuthenticaor, allows to authenticate a user with social provider (facebook, google, twitter, etc). You need to use the middleware CakeDC\Auth\Middleware\SocialAuthMiddleware and identifier CakeDC\Auth\Identifier\SocialIdentifier to make this authenticator work correctly. Check how enabled social authentication at users plugin.

• TwoFactorAuthenticator, used to complete the two-factor authentication. Configurations:

  • loginUrl: The login URL, string or array of URLs. Default is null and all pages will be checked.
  • urlChecker: The URL checker class or object. Default is DefaultUrlChecker.

Authentication Service

The custom authentication service allows you to use two-factor authentication and get a list of failure processed (see \CakeDC\Auth\Authentication\AuthenticationService::getFailures). When the authenticator get a valid result the service will proceed to two-factor verification, to ignore for a specific authenticator use the config key 'skipTwoFactorVerify'. Sample usage:

<?php
namespace App;

use Authentication\AuthenticationServiceProviderInterface;
use Authentication\Middleware\AuthenticationMiddleware;
use CakeDC\Auth\Authentication\AuthenticationService;
use Cake\Http\BaseApplication;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;

class Application extends BaseApplication implements AuthenticationServiceProviderInterface
{

    /**
     * Returns a service provider instance.
     *
     * @param \Psr\Http\Message\ServerRequestInterface $request Request
     * @param \Psr\Http\Message\ResponseInterface $response Response
     * @return \Authentication\AuthenticationServiceInterface
     */
    public function getAuthenticationService(ServerRequestInterface $request, ResponseInterface $response)
    {
        $service = new AuthenticationService();

        $fields = [
            'username' => 'email',
            'password' => 'password'
        ];

        // Load identifiers
        $service->loadIdentifier('Authentication.Password', compact('fields'));

        // Load the authenticators, you want session first
        $service->loadAuthenticator('Authentication.Session', [
            'skipTwoFactorVerify' => true
        ]);
        $service->loadAuthenticator('Authentication.Form', [
            'fields' => $fields,
            'loginUrl' => '/users/login'
        ]);

        return $service;
    }

    /**
     * Define the HTTP middleware layers for an application.
     *
     * @param \Cake\Http\MiddlewareQueue $middlewareQueue The middleware queue to set in your App Class
     * @return \Cake\Http\MiddlewareQueue
     */
    public function middleware($middlewareQueue)
    {
        // Various other middlewares for error handling, routing etc. added here.

        // Add the authentication middleware
        $authentication = new AuthenticationMiddleware($this);

        // Add the middleware to the middleware queue
        $middlewareQueue->add($authentication);

        return $middlewareQueue;
    }
