* Form authentication adapter for AuthComponent.

*
* ### Using Form auth
*
* Load `AuthComponent` in your controller's `initialize()` and add 'Form' in 'authenticate' key
*
* ```
* $this->loadComponent('Auth', [
* 'authenticate' => [
* 'Form' => [
* 'fields' => ['username' => 'email', 'password' => 'passwd'],
* 'finder' => 'auth',
* ]
* ]
* ]);
* ```
*
* When configuring FormAuthenticate you can pass in config to which fields, model and finder
* are used. See `BaseAuthenticate::$_defaultConfig` for more information.
*
* @see https://book.cakephp.org/4/en/controllers/components/authentication.html
