  5. Click I have Duo Mobile Installed.
  6. Activate Duo Mobile. On iPhone, Android, and Windows Phone activate Duo Mobile by scanning the barcode with the app's built-in barcode scanner. The Continue button is clickable after you scan the barcode successfully.
  7. Configure Device Options (optional):  If this is the device you'll use most often with two-factor authentication then we recommend you enable automatic push requests by clicking the When I log in: drop-down and changing the setting to Automatically send this device a Duo Push and click Save.
  8. Click Continue to login and proceed to the Duo Prompt. Your device is ready to approve two-factor authentication requests. Click Send me a Push to give it a try. All you need to do is tap Approve on the Duo login request received at your phone.
