Voice OTP Services

Securing Authentication
with Sound

Two-Factor Authentication (2FA) is a crucial element in protecting digital privacy for customers. However, there are instances where SMS-based 2FA may not be feasible. Fortunately, there are cost-effective and secure alternatives available. Voice 2FA serves as a reliable solution to deliver essential OTP (One-Time Password) messages to customers who cannot receive SMS OTP messages. This fallback mechanism is instrumental in ensuring user identification and verification, even in challenging circumstances.
