Login as Different User in SharePoint 2013 Preview

​When you login to SharePoint 2013 you'll notice the "Sign in as Different User" is missing from the Personal Menu.

Here are two workaround options:

1. Manually append the following URL to your site:
   
   /_layouts/closeConnection.aspx?loginasanotheruser=true
   
2. Add a Custom Action to the SharePoint Personal Menu:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    <CustomAction
												
    Id="MyLoginDifferentUser"
    GroupId="PersonalActions"
    Location="Microsoft.SharePoint.StandardMenu"
    Sequence="1000"
    Title="Sign in as Different User">
    <UrlAction Url="/_layouts/closeConnection.aspx?loginasanotheruser=true"/>
    </CustomAction>
</Elements>
