Can you protect against a SIM Swap attack? What is it? How does it work? And, what can we do about it? Famously, John Dorsey's Twitter account was taken over and sent some messages - because the bad actors took over his cell phone. That problem is avoidable. In Europe, when a person uses their phone app to manage money, the bank will ask the cell phone company if hte SIM car has changes in the past 48 hours. If it has, the bank will not allow the transaction to proceed. We could use something like that!
