  • My understanding was that the functionality was removed in SP2013 due to many bugs that it caused (first one I can think of is clicking on an Office document will open up Office as the currently logged in Windows user, not the one currently signed into SharePoint). As said below, the only supported way is to use the RunAs functionality to spawn the browser process as another user

There are several solutions to your problem as Microsoft has removed the Sign in as different user link.

  1. Start your browser as a different user

  2. Use the _layouts/closeConnection.aspx?loginasanotheruser=true page

  3. Edit the Welcome.aspx to include the link again (Sign in as Different User and SharePoint 2013)

  4. Use JavaScript as a Bookmarklet (SharePoint 2013 – Sign in as Another User)

  • i have added the code for enabling sign in as different user while click on that it is not moving to _layouts/closeConnection.aspx?loginasanotheruser=true page instead of this its moved to PageNotfound page Jun 7, 2017 at 10:07
  • even i have pasted this _layouts/closeConnection.aspx?loginasanotheruser=true and run the browser it goes ctv8vzq9b2srv01:13/Pages/… Jun 7, 2017 at 10:20
  • I guess there is something wrong in the URL which you have formed, can you pls share the url. Jun 7, 2017 at 10:43

as workaround you could just run IE(or other browser) as different user before log into the site

  • I have worked in IE edge and tried in all browser too Jun 7, 2017 at 8:56
