IE8 login multiple account without installing plugins

This problem, in fact, is because the browser must contain (cookies) The reason, this problem in front of the IE8 browser can easily handle it. When you start IE8, log on to the first account, and then close the ALT key to activate the menu bar, select File/New session, open a new IE8 browser window, and then you can log on with the second account. If you have a third account, you can select the menu file/new session again to create a new IE window, and then log on to the account. By analogy, you can continue to log on with more accounts.

IE8 can log in with more than one account, in the final analysis because the new session generated by the IE window does not share cookies with the original IE window, so the account that is logged in to the previous IE browser window will not cause any information interference to the newly produced IE window.
