I am all for a more robust network and fallback infrastructure, but SMS is not very secure. It's not encrypted and SIM swap attacks are common. Are there ways around those concerns?

I’m minimally tech savvy and know nothing about SMS so I have no good answers for you unfortunately.
I want to see some of the brightest in #Bitcoin work on this problem though. Huge market if they could build something secure and open source and it really would level up the Network’s resilience. No more grid / internet outage FUD and would make Bitcoin true apocalypse money.
