MultiAntivirus is integrated with the OpenNotify project.
OpenNotify uses a separate, completely anonymous user management system (no registration required).
It is directly the OpenNotify client (.dll) that generates a random identification code, which can be used at the user's discretion to unify their notifications.
So by setting the same code on all your devices (and with network access) you can unify your notifications.
Please note that notifications will be saved on the server in order to be downloaded and displayed by all devices in possession of the random user code.
To see your own notifications on this page, add your own random user code:
