Duo Mobile does not require a constant internet connection to generate passcodes, as it can create one-time codes offline. However, an internet connection is needed for push notifications and to register new devices.

You can contact Duo Mobile support through the Duo Security website, where support resources are available, or you can submit feedback directly through the app settings.

You can manage or cancel your Duo Mobile subscription through the account settings in the application or by visiting the Duo Security website, where you can find options for subscription management.
