An enhancement was made to the public Open Vehicles server today:
From now on, the first time a vehicle incorrectly logs in (wrong server password) to the server, a PUSH notification alert will be sent to all registered applications for that vehicle. If such a failed authentication vehicle subsequently successfully connects, another notification alert will be sent to indicate that the authentication was now successful.
We've done what we can to arrange for only one of each alert to be sent, and hope that these prove useful both for initial setup of the vehcle and ongoing monitoring.
