I wonder what the footprint is do the SIM hijacking, e.g. is anyone a sufficiently high enough bribe away from the type of scheme that compromises their account because it only takes 1 employee to effect it.
I've been switching to hardware keys when I'm able but it's not always feasible. I just bought a Titan key combo and you can't use most 3rd party email clients with it so that made it kind of useless to me (since Gmail's mail app isn't that great)
