To allow trusted friends and even yourself to use the VPN service, you must first add them in the app.
To do so, please visit Menu > Friends and tap on plus the icon on the top right corner.
Then enter your friend's email address as well as a shared secret phrase between you and your friend. "Shared Secret" is basically a phrase that will be included in all emails, proving to your friend your device sent them.
Your WEPN device will then email the connection key to them, along with instructions to connect.
