Forget his login information - you don't need it.
Load the appropriate version of DJI Go on your phone.
It will ask for your email address to register an account at DJI
Fly.

Make sure you Have DJI Go 4 installed, not DJI GO (that is for older drones). Also make sure you have it properly connected with the USB cable to the RC.
