Your brokerage has a safety net built in: the trusted contact. It's someone you pick in advance—a backup person your exchange will reach out to if they spot red flags suggesting your account might be vulnerable to fraud or financial exploitation. Think of it as having a security checkpoint. If suspicious activity gets detected, that designated contact becomes your first line of defense, getting alerted before things potentially spiral. It's one of those features worth setting up even if you hope never to need it.
