If you need assistance enrolling your token or have questions which are not answered by the VUMC MFA web site, contact your local IT support provider or call the VUMC Help Desk at 3-HELP (61). If you are a Feinberg faculty, staff member, or student, you are required to use this VPN client before accessing your email account, whether you are on campus or off campus. If someone steals your username and password but doesn't have your phone, they will not be able to impersonate you and access the system.
