Challenges with
OTP authentication

SavingPiggyCoins

Expensive

Whether businesses maintain their own messaging infra or use a third-party, OTP costs quickly add up and are not scalable.

Alert Triangle

Security gaps

While safer than passwords, SMS authentication is prone to phishing, MITM, and OTP fatigue attacks.

Caret Down

Unreliable

OTPs depend on phone connectivity, making them unsuitable for international travel and prone to droppages.

User

User fatigue

Users are growing tired of endless OTPs, weakening their perception and making users more prone to social engineering.
