Duo Security Token
If you do not have a second device to use for authentication, Duo
Security Tokens may be checked out or purchased from the Technology
Support Center (TSC). These security tokens generate an authentication
code that can be used to verify your account. Restrictions are
associated with token checkout so please review the below information
ITS recommends purchasing a token only if you have no other means for authenticating your device (alternative methods include mobile phone, tablet, office phone, etc.). Purchased tokens are meant to be used for an extended period of time.
