Set the default device

Duo automatically identifies the last device used based on browser cookies with no manual selection option. This tracking is specific to each browser and device. Since Duo uses the Central Authentication Service (CAS), all related services are treated as a single application. For more details, see How does the Duo Universal Prompt last-used authentication method work? on Cisco Duo's website.
