You can use vCenter Single Sign-On with Windows Session Authentication (SSPI). To make the checkbox on the login page available, you must install the Client Integration Plug-in.

About this task

Using SSPI speeds up login for the user who is currently logged in to a machine.


Your Windows domain must be set up properly.


  1. Navigate to the vSphere Web Client login page.
  2. If the Use Windows session authentication check box is not available, click Download the Client Integration Plug-in at the bottom of the login page.
  3. If the browser blocks the installation by issuing certificate errors or by running a pop-up blocker, follow the Help instructions for your browser to resolve the problem.
  4. Close other browsers if you are prompted to do so.

    After installation, the plug-in is available for all browsers.

  5. Exit and restart your browser.

    After the restart, you can select the Use Windows session authentication check box.
