While using the Duo two-factor authentication mobile app is the best and recommended authentication option, it is also recommended that users generate and safely store a list of backup single-use codes that can be used when:
you do not have immediate access to your previously registered device
if you change devices or phone numbers
your device is not working
These backup codes can be entered in lieu of your other, regular authentication method.
Follow the instructions below to generate new single use codes. These instructions apply when using a mobile device for two-factor authentication.
