USER EXPERIENCE AND FRICTION

SMS OTP adds visible friction: users wait for a message, retrieve it, enter it, and can still fail. SNA is attractive because it can make verification smoother and more aligned to the mobile journey.

 

  • Security and phishing risk

    • SMS OTP remains exposed to phishing and other weaknesses that make it less attractive in higher-risk environments. SNA is increasingly interesting because it changes the trust model and reduces dependence on a highly interruptive step.

  • Commercial case for change

    • The question is no longer only whether SMS OTP works. The question is whether it is still the right answer when businesses care about conversion, support cost, fraud, and mobile-first design.

  • How to evaluate the transition

    • The right comparison should look at use case, friction, risk, rollout complexity, and where SNA can deliver the strongest business case first.
