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.
