The parent comment was asking about GA vs Authy. Responses were like GA is better because there's no SMS. This is true if you look at GA vs Authy mobile apps.

The parent comment was asking about GA vs Authy. Responses were like GA is better because there's no SMS. This is true if you look at GA vs Authy mobile apps. This is false, if you look at the consumer services where you enabled 2fa (Google, Facebook, Twitter, Instagram, Coinbase, Twitch...). They all require SMS to setup 2fa, and let you use SMS to bypass GA. You can not bypass GA with an SMS (the TOTP), you can bypass the service 2fa, because for availability reasons they must provide you more than a single 2fa method.
