GoogleAuthenticate plugin

Plugin containing Google 2 step authenticate class for AuthComponent.

Includes libs from https://github.com/chregu/GoogleAuthenticator.php with some minor adjustments

Requirements

  • PHP 5.3
  • CakePHP 2.x

Installation

[Manual]

  1. Download this: http://github.com/ceeram/GoogleAuthenticate/zipball/master
  2. Unzip that download.
  3. Copy the resulting folder to app/Plugin
  4. Rename the folder you just copied to GoogleAuthenticate

[GIT Submodule]

In your app directory type:

git submodule add git://github.com/ceeram/GoogleAuthenticate.git Plugin/GoogleAuthenticate
git submodule init
git submodule update

[GIT Clone]

In your plugin directory type

git clone git://github.com/ceeram/GoogleAuthenticate.git GoogleAuthenticate

Usage

In app/Config/bootstrap.php add: CakePlugin::load(‘GoogleAuthenticate’);

Configuration:

Setup the authentication class settings.
You dont need Form authenticate anymore, as it will only check the code if secret field in users table is not empty.
If secret field is empty, it will behave like normal Form authenticate.

If you would combine Google 2 step with Form, make sure you set a scope on your Form authenticate

'scope' => array('User.secret' => null)

Example for GoogleAuthenticate:


    //in $components
    public $components = array(
        'Auth' => array(
            'authenticate' => array(
                'GoogleAuthenticate.Google' => array(
                    'fields' => array(
			'username' => 'username',
			'password' => 'password',
			'code' => 'code',//fieldname in form
			'secret' => 'secret'//fieldname in table
		),
		'userModel' => 'User',
		'scope' => array()
                )
            )
        )
    );
    //Or in beforeFilter()
    $this->Auth->authenticate = array(
        'GoogleAuthenticate.Google' => array(
            'fields' => array(
			'username' => 'username',
			'password' => 'password',
			'code' => 'code',
			'secret' => 'secret'
		),
		'userModel' => 'User',
		'scope' => array()
        )
    );

Usage

Above configuration is what is needed to be able to login using the adapter.
You need to generate a secret code and store it in your users table.

You can show the secret code to the user, or display a QRcode.

Here is an example action in UsersController which handles all this:


/**
 * Displays secret code and QRcode for the user account.
 * Will create a secret, if not set in users table
 *
 * Also handles removal of secret from database with Form->postLink(), to allow normal login again.
 *
 * To generate a different secret, browse to http://domain.com/users/secret/renew
 *
 * @return void
 */
	public function secret($renew = null) {
		$this->User->id = $this->Auth->user('id');
		if ($this->request->is('post')) {
			$this->User->saveField('secret', null);
			$this->redirect(array('action' => 'view', $this->User->id));
		}

		App::uses('GoogleAuthenticator', 'GoogleAuthenticate.Lib');
		$Google = new GoogleAuthenticator();

		$secret = $this->User->field('secret');
		if (!$secret || $renew == 'renew') {
			$secret = $Google->generateSecret();
			$this->User->saveField('secret', $secret);
		}

		$url = $Google->getUrl($secret, $this->Auth->user('username'), 'example.com');

		$this->set(compact('secret', 'url'));
	}

And the secret.ctp view template for this action would be:


<div class="users secret">
	<h2><?php echo __('Google secret'); ?></h2>
	<div>Enter this code manually: <?php echo $secret;?></div>
	<div>Or scan the QRcode: <?php echo $this->Html->image($url);?></div>
</div>
<div class="actions">
	<h3><?php echo __('Actions'); ?></h3>
	<ul>
		<li><?php echo $this->Html->link('Generate different secret', array('action' => 'secret', 'renew'));?></li>
		<li><?php echo $this->Form->postLink('Remove secret');?></li>
	</ul>
</div>
