OTP SMS: Secure and Instant User Authentication

OTP SMS (One-Time Password SMS) is a highly secure method for authenticating users by sending a unique, temporary code directly to their mobile phones via SMS. This code is valid for a single use and expires quickly, significantly reducing the risk of unauthorized access and enhancing overall cybersecurity.

Widely used across various industries, OTP SMS offers a reliable way to verify user identity during logins, transactions, and sensitive operations. It is easy to implement, accessible to almost all users with mobile phones, and plays a crucial role in two-factor authentication (2FA) systems.
