Sign in as different user in SharePoint 2013

Sign in as different user has been removed from the SharePoint 2013 could be because of the users switching between accounts and making customizations to the existing page directly.


below is the way we can make it appear on the SharePoint sites:-

Locate the file \15\TEMPLATE\CONTROLTEMPLATES\Welcome.ascx and open in a text editor.

 Add the following element below the existing element "ID_PersonalInformation"


<SharePoint:MenuItemTemplate runat="server" ID="ID_LoginAsDifferentUser"
 Text="<%$Resources:wss,personalactions_loginasdifferentuser%>"
 Description="<%$Resources:wss,personalactions_loginasdifferentuserdescription%>"
 MenuGroupId="100"
 Sequence="100"
 UseShortId="true"
 />


And Now save the file. Do it on all the SP servers. Refresh the site now and you should be able to see it.
