On this page, you'll find information about commonly used Duo approval methods. We recommend having at least two devices set up so you have a backup if you do not have access to one. (To read more about Duo and how two-factor authentication works at Smith, see the Duo topics page.)
To make any changes to your Duo devices, you must access the Duo Manage Devices settings on a web browser. See How to Add a New Device below for instructions.
You'll receive an email from Duo confirming when changes have been made to your devices. This helps protect your account from unauthorized activity. If you receive an email and you have not made any changes in Duo, your account may be compromised. Follow the instructions to change your Smith account password and report the event.
