OTP has become essential in preventing fraud and keeping your customers’ and business’ data safe.
Want to know more about OTP and what it can do for your business?
In this guide, you’ll learn what OTP means and how it works so that you can implement it in your business.
OTP stands for one-time password. It is sometimes called a one-time authentication code, one-time pin, or one-time code. Whatever it is called, it means the same thing.
It looks like this:
Example of OTP display
It’s a temporary code that provides an extra layer of security when accessing a system or service. OTPs are used alongside a username and password to create what is known as two-factor authentication.
When an OTP is required to log into an account or complete a transaction, you must enter the OTP in addition to your login credentials to gain access.

OTP authentication (also called OTP verification) is a form of 2FA (two-factor authentication) that uses OTP codes to verify a user. It is a method that a website or app uses to verify your identity when you try to gain access.
2FA requires you to provide two authentication factors to access an account. One of these factors is “something you know” (such as a password or PIN), while the other is “something you have.” This can be your smartphone, a security token, or an OTP.
In the case of OTP authentication, the “something you have” is a device that receives the OTP and provides it back to the system as proof of authentication.
You can send OTPs via SMS, WhatsApp, or email. They are only valid for a short time, usually a few minutes.
OTPs can also be sent via voice messages and special token devices.
Now that we have an idea of what OTP means, let’s move on and learn how OTP works.
Here’s how an OTP works:
For an OTP payment, a user initiates a login or transaction. The system then generates a one-time password.
The OTP is securely delivered to the user via SMS or email.
To complete the authentication process, the user enters the OTP within a specific time limit. This OTP code authorizes the user to complete the transaction.
To do this, you need an OTP platform.
An OTP platform is a service or software solution that lets you generate and send OTPs.
The platform handles the generation and sending of the OTP (and all the technicalities that come with it), so you don’t have to do it yourself.
An OTP platform includes the following components:
A way to generate OTPs.
A server-side application or a third-party service.
A method of delivering OTPs to users. It could be via SMS or email.
A system that ensures secure access only with a valid OTP.
A user management system that allows administrators to manage users and assign permissions and roles.
You can create your own OTP SMS. Here’s a step-by-step guide on how to set up OTP for SMS, send OTP to phone numbers, and integrate an OTP service into your website:
Sign up with an OTP service provider: An OTP service generates unique temporary passwords and delivers them securely to users via SMS or email. You can use smsotpverify’s SMS API services for this.
