You have a choice to either set up one account and manage multiple locations from within the WiFi Your Way App OR you can set up a different account for each location.
If you set up all your locations under one account, here is how you can access each location:
Open the WiFi Your Way Work App on your device
Navigate to the “Settings” page by tapping on the gear button (in the top right corner on iOS devices).
Scroll down to “Account” and you can switch between locations.
