This notification checks all of your active social media profiles by logging into them individually. Any profile that VSys is unable to log into will generate a notification so that you can re-authorize the profile.
Because of the nature of how the social media sites work, VSys doesn't know your login ID and password for your accounts. Instead VSys uses OAuth which has you log into the social media sites, then it records a "token" that it can use in the future without your having to manually log in. If/when that token expires or becomes invalid, you need to re-authorize that profile.
