🔒 Reactivate DUO Two-Factor Authentication on a New Mobile Device

Duo Two-Factor Authentication is an additional security method that Cedarville promotes in order to increase University account security for participating students, faculty, and staff.  Per our network account management policies, we do not provide Duo to alumni accounts.  Alum can set up Microsoft Authenticator for similar protections through https://selfservice.cedarville.edu/CedarInfo/TwoFactorEnrollment. For more information, see the help page Two-Factor Authentication FAQ.

When participants of Two-Factor Authentication receive a new smartphone (with the same phone number), the Duo Push ("Send me a Push") authentication method no longer works. To log in to your account, you must use a bypass code. Call Information Technology at +1-937-766-7905 to be issued a bypass code. 

To learn how to reactive your smartphone, read the instructions below.
