What is OTP?

In today's digital landscape, security is paramount. As cyber threats continue to evolve, businesses and individuals alike are seeking more robust methods to protect their sensitive information. One such method that has gained popularity is OTP verification. OTP, or one-time password, is an authentication technique that provides an additional layer of security by generating a unique password for each login session or transaction.

A research reveals that OTPs accounted for 88.57% of total international traffic in 2022. The traffic level will sustain as more brands looks for OTP SMS in order to provide user security, authentication and seamless experience.

In this comprehensive guide, we will explore the concept of OTP verification, its benefits, and how you can implement it to enhance security and user experience.

Understanding OTP Verification

OTP verification is a process that ensures secure access to accounts, networks, or systems by generating a one-time password that is valid for a single login session or transaction. Unlike traditional static passwords, which can be easily compromised, OTPs provide an added level of security as they are unique and change with each login attempt.

OTP SMS is one of the most adopted use cases of A2P SMS across the industries. As per a report by Mobilesqaured, the A2P messaging spend will peak in 2024 with businesses investing $37.13 billion on SMS with OTP SMS being the majority of the same.

OTP verification can be implemented in various ways, depending on the specific requirements of a system or application. The most common methods include:-

a. SMS OTP verification,

b. Email OTP verification, and

c. App-based OTP verification.

These methods leverage different channels to deliver the one-time password to the user, ensuring secure access and reducing the risk of unauthorized access.

Who is an OTP SMS Provider?

An OTP SMS provider in India is a company or service that offers the technology and infrastructure to generate and deliver one-time passwords to users for various authentication and verification purposes.

OTP service providers offer APIs (Application Programming Interfaces) and platforms that businesses and organizations can integrate into their applications or systems. These OTP SMS APIs allow them to generate and send OTPs to their users securely and efficiently. The OTP service provider handles the back-end processes of generating unique passwords, ensuring their secure delivery, and managing the overall authentication process.

With WhatsApp OTP being 99% cheaper than OTP SMS, it will be interesting to see the path that OTP service providers take in 2024 to capture the market. Although, SMS shows the speed and interaction level that no other channel come close to delivering.
