-This means however, that once a robot has been configured to access your WiFi it never needs to communicate with EcoVac's servers again.
+The EcoVacs app encrypts the username/password with the public key of EcoVacs when authenticating.  Since we don't have the private key to decrypt, there is no way to provide true security and authentication.
