    OTP SMS Service

    Fast. Secure. Reliable User Authentication

    OTP SMS (One-Time Password SMS) is a critical service used to authenticate users during logins, transactions, registrations, or sensitive actions. Delivered instantly to the user’s mobile number, OTPs act as a second layer of security - ensuring the identity of the user is verified in real time, thereby preventing fraud, data breaches, and unauthorized access.

    At Adithya Adsme, we provide high-speed, scalable OTP SMS solutions built to handle thousands of verification requests per second - ensuring seamless security for your platform and peace of mind for your customers

    What Is OTP SMS?

    An OTP SMS is a system-generated, time-sensitive numeric or alphanumeric code sent to users’ mobile phones for one-time use during:

    Login Authentication

    Password Reset

    Payment Authorization

    New Device Login

    Two-Factor Authentication (2FA)

    Registration & Sign-up Validation

    OTPs are valid for a short duration (e.g., 30–60 seconds) and are unique per transaction/session. They’re a widely accepted industry-standard method of secure identity validation.

    Example of OTP SMS:

    Dear Customer,

    Your OTP is 127845. It is valid for the next 5 minutes. Please do not share this with anyone.
