I’m also curious about this question as I’ve had some shit happen to one of my FB Ads account, just after I connected to a public hotel wifi.

Because of this I’ve lost access to the account and with this, months of data from some Pixels.

Oh man, i literally had to go back to the border of my home country to get signal for the local number in order get the sms verification to change the number to a new one… That was a pain for sure.
