SP2013: How to Sign in as Different user

Hi,

Was quite simple in SharePoint 2010 but the "Log on as Different User" the has been removed in SP2013.
I Used it quite often.

SP2010:

This menu is not available on SP2013.
Work arounds:
1:
Hold down shift and right click Internet Explorer, choose Run as different user

 Here is can supply the details of the user you want to log in as.

2:
You can acces the site with the following url:
http://<site url>/_layouts/closeConnection.aspx?loginasanotheruser=true

You can enter the details here.

Cant imagine why they would remove the link...
