How to Set Up DUO Mobile App

Warning

Be sure to add more than one device to the devices portal. It is recommended that when setting up DUO, the mobile phone with DUO app is added first, then an office phone is added second. This will maintain the correct device order in Global Protect. This is very important in the case that your main device (usually a cell phone) is lost or dead.
