Choose a Different Method
If you ever want to choose a different device or Duo method than the one shown automatically by the Universal Prompt, click Other options near the bottom. This takes you to a list of all your available Duo authentication options. Click on the one you want to use and follow the instructions shown to complete logging in to the application.
Default device setting
The Universal Prompt does not have a way to configure a default authentication device. Instead, it will always prompt you for your last-used authentication method. If you select an option and authenticate with it, Duo will remember and continue to automatically prompt you with it until you authenticate with a different method.
