  • I think it’s because TOTP requires some sort of initial token sync that is more complicated than entering a telephone number. There’s also no need to have people backup codes etc. To use Authy for example I need to photograph a QR code and have a smart phone.

    Text message as a solution works on older non-smart phones so it’s possibly the “most widely accessible” solution.

    From a backend perspective as well it’s just an API text $random to $phone.
