You can do it this way:

Every backend action controller have access to the $this->_auth variable which is an instance of \Magento\Backend\Model\Auth declared in the constructor of Magento\Backend\App\AbstractAction.

To check if an admin user is logged in you can use:

$this->_auth->isLoggedIn()

In your controller.

In case you're not working with a controller you can use Dependency Injection in your constructor:

protected $_session;

public function __construct(
    \Magento\Framework\Model\Context $context,
    \Magento\Backend\Model\Auth\Session $authSession
) {
    $this->_session = $authSession;

    parent::__construct($context);
}

And then call:

$this->_session->isLoggedIn()

Well that's an interesting one, I reckon you should see with Alan Storm if he made an M2 version of his module: https://github.com/astorm/Magento_CrossAreaSessions/ – Raphael at Digital Pianism Mar 17 '16 at 10:34
Ok, I will ^^ Thank you again @RaphaelatDigitalPianism – JuanP Barba Mar 17 '16 at 10:51

My source below may some helpful.

events.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="backend_auth_user_login_success">
        <observer name="name_of_observer_for_backend_auth_user_login_success" instance="\Instance\Class\Name" />
    </event>
</config>

Then create the observer.

class BackendAuthUserLoginSuccess implements ObserverInterface
{
    const DEFAULT_SESSION_NAME_OF_FRONTEND = 'PHPSESSID';

    /**
     * (non-PHPdoc)
     * @see \Magento\Framework\Event\ObserverInterface::execute()
     */
    public function execute(\Magento\Framework\Event\Observer $observer) {
        if (! isset($_COOKIE[self::DEFAULT_SESSION_NAME_OF_FRONTEND])) return;
        $backSessionId = session_id();
        $frontendSessionId = $_COOKIE[self::DEFAULT_SESSION_NAME_OF_FRONTEND];
        session_write_close();
        session_id($frontendSessionId);
        session_start();
        $_SESSION['admin'] = [$backSessionId];
        session_write_close();
        session_id($backSessionId);
        session_start();
        return;
    }
}

Now after admin login then you can get admin session id by front-end session in $_SESSION['admin'], and you can use session_id($_SESSION['admin'][0]) switch session details and continue.

This code need front-end session id already created, so must add one iframe (src=frontend.anypage) to backend/auth/login page.
