Challenges with OTP authentication
Expensive
Whether businesses maintain their own messaging infra or use a third-party, OTP costs quickly add up and are not scalable.
Security gaps
While safer than passwords, SMS authentication is prone to phishing, MITM, and OTP fatigue attacks.
Unreliable
OTPs depend on phone connectivity, making them unsuitable for international travel and prone to droppages.
User fatigue
Users are growing tired of endless OTPs, weakening their perception and making users more prone to social engineering.
