NOTE: In order to take advantage of the options below, be sure to register your device(s) for use with your MFA account (including, if applicable, downloading and installing the Duo Mobile App on your smartphone) before you begin your travel.

Notes
- Public wireless hotspots generally provide unsecure networks that could allow others to access your information. Make sure to use the USC VPN whenever you connect to USC systems via a public wireless connection, including hotel, convention center, and café wireless networks. Use of a VPN will protect your personal information by encrypting it over open networks. For more information about VPN, see itservices.usc.edu/vpn.
- If you do not have access to a smartphone or tablet that you can use for MFA while traveling, please contact the ITS Customer Support Center for assistance.
