OTP SMS

OTP (One-Time Password) Info SMS service uses text messaging to deliver one-time passwords (OTP) to users for secure verification purposes. OTP SMS is a standard second-factor authentication method, provides an extra layer of security during online activities making it harder for unauthorized access. without an internet connection users receive OTPs directly on their phones, a device they likely carry most of the time.

How it works-

A user attempts to log in to a website, app, or perform an action requiring verification (e.g., financial transaction).
The system triggers an SMS containing a unique, temporary code sent to the user's registered mobile number.
The user enters the received OTP code on the login/transaction page to complete the process.
