The similar question was asked many times before and it seems that it stil haven't complete solution. My answer will be based on already solved solutions published here:

If you want to have single account for all multi-stores you have to do the following:

1 Share customer accounts

You can configure this feature here: System -> Configuration -> Customer Configuration -> Share Customer Accounts.

2. Share sessions between Magento websites.

There are 3 possible store configurations:

1. If your websites are located in one domain, but in different directories, e.g. "www.example.com/stores/store1" and "www.example.com/stores/store2" you can setup your "Cookie Path" to "/stores/" in System -> Configuration -> Web -> Session Cookie Management.

2. If your websites are located in different sub-domains e.g. "store1.example.com" and "store2.example.com" you can setup "Cookie Domain" to ".example.com" in System -> Configuration -> Web -> Session Cookie Management.

3. If you have different domains, in this case you can add session ID to the URL for another store. Use this construction "Mage::getModel('core/url')->addSessionParam()->getUrl('...')" to get the URL with session parameter.

After that your customers will be able to switch between multi-stores Magento websites without re-login. In other words, if customer will login in one Magento website, he will be able to see another multi-store Magento website using his first store account.

There is also a code based solution.

• Overwrite magento/app/code/core/Mage/Customers/Model/Customer.php and change again the method getSharedWebsiteIds() to:

        public function getSharedWebsiteIds() { 
            $ids = $this->_getData('shared_website_ids'); 
            if ($ids === null) { 
                $ids = array(); 
                if ((bool)$this->getSharingConfig()->isWebsiteScope()) { 
                    $ids[] = $this->getWebsiteId(); 
                } else { 
                    foreach (Mage::app()->getWebsites() as $website) { 
                        $ids[] = $website->getId(); 
                    } 
                } 
                $this->setData('shared_website_ids', $ids); 
            } return $ids; 
        }

• overwrite magento/app/code/core/Mage/Core/Model/Session/Abstract/Varien.php

and

replace this

// potential custom logic for session id (ex. switching between hosts)
$this->setSessionId();

with

// potential custom logic for session id (ex. switching between hosts)
/* Amend to ensure shopping carts are shared between websites */
if (isset($_COOKIE['lastsid']))
{
  session_decode(file_get_contents(Mage::getBaseDir('session').'/sess_'.$_COOKIE['lastsid']));
            setcookie ('lastsid', '', time() - 3600);
        }

        if (isset($_GET['SID']))
        {
            $this->setSessionId($_GET['SID']);
            session_decode(file_get_contents(Mage::getBaseDir('session') . '/sess_' . $_GET['SID']));
            setcookie('lastsid', $_GET['SID']);
            $_COOKIE['lastsid'] = $_GET['SID'];
        }
        else
        {
            $this->setSessionId();
        }
        /* Amend end */
