The authorization of your device in Wassenger should be a one-time process (unless you deauthorize it on purpose), but there are a few cases where it might happen that your device gets deauthorized. Please find below the most common scenarios and how to solve this problem.
You have too many WhatsApp linked devices active
At the moment WhatsApp allows you connect several WhatsApp Web / Desktop linked devices. One of these device sessions should be connected to Wassenger in order to send and receive messages through the platform.
It often happens that you may have to delete a linked device in order to connect a new one, and by mistake the deleted one is the one linked to Wassenger. This will cause the service to stop sending and receiving messaging through your WhastsApp number, requering you to re-connect the session by replacing or creating a new linked device from the WhatsApp mobile app.
