Configure Duo Security integration for iPhones and iPads

Perform the following steps to let Duo Security determine the trust status of your iPhones and iPads.
  1. Configure the connection to the Duo certificate server:
    1. On the menu sidebar, under SETTINGS, click Setup > Sophos setup, and then click the Duo Security tab.
    2. Enter the settings provided by Duo Security.
  2. Add a Duo device certificate configuration to the device policy you are using for your iPhones and iPads.
  3. Run the Update devices device action.

This installs a Duo device certificate on the devices. The Duo Mobile app detects the certificate and classifies the devices as trusted.
