When I open explorer to check my email I don't have to type my password in for the new mail. How do I keep that from happening? I don't have the mail checked to remember the number. This a shared computer and I don't want anybody to see my mail.  ***  is the number for the public not *** . If I have to have this set-up on windows 8 then let it be ***.

Note: I have removed the email addresses for security reason.
