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 familiar phrase between you and your friend. "Familiar Phrase" is not a password, and will be sent to them in plain text. It is a phrase, agreed upon between you and your friend, that will be included in all emails. It proves to your friend your device sent that email, and prevents your friends to be sent a fake email which pretends to be from your device.
Your WEPN device will then email the connection key to them, along with instructions to connect.
