    </referenceBlock>

Answer 1

Use below code for remove sign in link

 <referenceBlock name="authorization-link-login" remove="true" />

Answer 2

You should remove the 'authorization-link-login' block in default.xml file of your theme.

 <referenceBlock name="authorization-link-login" remove="true"/>

Remember to flush cache after that.

Answer 3

If you want to hide and show header with respect to customer login/logout

add this in body of file app/design/frontend/vendor/theme/Magento_Theme/layout/default.xml

<referenceBlock name="header.links">
            <block class="vendor\module\Block\Headerlinks" name="history-link" after="my-account-link">
                <arguments>
                    <argument name="sortOrder" xsi:type="number">100</argument>
                </arguments>
            </block>    
        </referenceBlock>

and in file Headerlinks add

    <?php
namespace vendor\module\Block;


class Headerlinks extends \Magento\Framework\View\Element\Template 
{
    protected $customerSession;

    /**
     * Construct
     *
     * @param \Magento\Framework\View\Element\Template\Context $context
     * @param \Magento\Customer\Model\Session $customerSession
     * @param array $data
     */
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
         array $data = [],
         \Magento\Customer\Model\SessionFactory $customerSession
    ) {
        parent::__construct($context, $data);
        $this->customerSession = $customerSession;
    }

    /**
     * Render block HTML
     *
     * @return string
     */
    protected function _toHtml()
    {
        $customer = $this->customerSession->create();
        if ($customer->isLoggedIn()) {
             $link = '<li><a href="' . $this->getUrl('customer/account/') . '" title="Account & Security">Account & Security</a></li>';
             $link .= '<li><a href="' . $this->getUrl('sales/order/history/') . '" title="Purchase History">Purchase History</a></li>';
        return $link;
        }
        return;
    }
}
