Phones are a very good solution for 2FA, considering the requirements to obtain a phone number. The only disadvantage afaict is that SMS communication is easily intercepted and not encrypted.
- lotsofpulp 3y agoI thought the requirements were being a near minimum wage employee at mobile network store (in the US) or a call center employee. Which is usually how SMS 2FA are stolen, and no one is liable for the consequences. Which means SMS 2FA is pretty low security. Convenient for most, but secure? Hardly.

When you are getting a new phone number you need to provide your ID card which has a chip and it is read by a device in order to tie the number to your ID for the phone number to be activated. I assume some cryptographic signing scheme is in action.
