Class FormAuthenticate

Form authentication adapter for AuthComponent.

Allows you to authenticate users based on form POST data. Usually, this is a login form that users enter information into.

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.

Parameters

Cake\Http\ServerRequest $request: The request that contains login information.
Cake\Http\Response $response: Unused response object.

Returns

array|false
