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.

Config.xml code:

<global>
...
  <models>
    <magento85915>
      <class>StackOverflow_Magento85915_Model</class>
    </magento85915>
  </models>
    <events>
    <controller_action_predispatch> <!-- identifier of the event we want to catch -->
        <observers>
          <controller_action_predispatch_handler> <!-- identifier of the event handler -->
            <type>model</type> <!-- class method call type; valid are model, object and singleton -->
            <class>magento85915/observer</class> <!-- observers class alias -->
            <method>adminRedirection</method>  <!-- observer's method to be called -->
          </controller_action_predispatch_handler>
        </observers>
      </controller_action_predispatch>
    </events>
  </global>

observer code:

<?php
class StackOverflow_Magento85915_Model_Observer
{

          public function adminRedirection(Varien_Event_Observer $observer)
          {
              $controller_action= $observer->getEvent()->getControllerAction();
              $request=$controller_action->getRequest();

              // redirection fire when current store is not aadmin
              if (!Mage::app()->getStore()->isAdmin()):
              // Get admin log page url
               $url=   Mage::helper('adminhtml')->getUrl('adminhtml/index/login');
              /* forcefull redirection  to admin login page */
                   Mage::app()->getFrontController()->getResponse()
                              ->setRedirect($url)
                                        ->sendResponse();
                        exit;
                  endif;
              return true;
        }



}
