I think I was too focused on answering your question regarding security :). Basically, yes we do offer security, and the security we offer prevents social engineering. But that is not the only point of the product.
SMS OTP is used in general as a way to authenticate, on any kind of app, because it's the only seamless option to reach these types of users. And since SMS OTP is more expensive than our pricing and requires integration with several local providers for a good delivery rate, these developers can simply use Cotter because it's easier to integrate, it works across apps so it reduces friction and SMS cost, and it provides security from day one.
So the value is not only about the threat/risk assessments but it's just a better alternative to SMS OTP logins. Our goal is to make our product faster, cheaper, and better than their current options to authenticate users.
Let me know what you think about this! And thanks for talking about this, it really got us thinking.
