Internet Explorer’s Different User Option

 Internet Explorer’s Different User Option

The most common way to sign in as a different user is with Internet Explorer’s “Run as different user” option. Just right-click the IE icon while holding the shift key down and click on “Run as different user.” Once logged in, just navigate to the SharePoint site. This method is quite cumbersome but it does allow you to run multiple instances of IE and be logged in as a different user in each one.

Note for the Windows 7 or 8 users: if you have IE pinned to your taskbar, holding the shift key and right-clicking on the taskbar icon won’t work. You have to right-click the IE icon in the taskbar first, then hold the shift key and right-click on the Internet Explorer option.
