Text forwarding is indeed a HUGE security risk with 2-factor authentication or password recovery.

I’m currently unsure if ATT offers the option to completely disable Call Forwarding, without breaking other features / services.
I was able to call customer service and with relative ease have a customer service rep enable Call Forwarding. Which is a bit scary, considering the bits of information they use to “authenticate” me were minimal and could be gleaned from other sources.
FTA “There's a constant tension between providing a good customer experience and protecting security and privacy.”
I understand this all to well. Bad customer service review can severely negatively affect a customer service rep’s job.
Bottom line. TEXT FORWARDING IS BAD.
