Are You Choosing the Right OTP SMS Service Provider? Major Aspects to Consider!

Introduction

Cyber crimes are now a well-known reality. With this data security is a pressing need for everyone. Data security has many forms that ensure secure data transactions ensuring that data exchange happens only between the rightful owner and receiver. One such form of mechanism is the One-Time Password or OTP which ensures authorized users have access to the desired data in the form of sensitive information. OTP service providers or OTP SMS service providers as they are called help in this process ensuring safe and secure data exchange between authorized parties. In this article, we will talk about this OTP SMS service, how it works, and how to choose the right OTP SMS service provider.

What is SMS OTP Verification?

SMS OTP (One-Time Password) verification means generating passwords for single-use or one-time use and sending via SMS to the authorized mobile phone intended for the phone owner to use them. It adds an extra layer of security making it tougher for cyber criminals to get access to sensitive information and misusing the data. It can be 4-6 numeric or alphanumeric single-use codes sent to the recipient for a particular session or authentication to access a specific service. It expires within a specified time, usually in 5-10 minutes. Beyond this period the code becomes inactive for use.

SMS OTP Verification: How Does It Work?

Here are the steps of how the entire cycle happens from start to end.

1. Request Generation

When a customer or a user initiates some action that needs verification (such as logging in to an e-commerce site or making a transaction etc.), the system generates an OTP request.

2. OTP Generation

The OTP request in turn prompts the OTP service to generate a unique, temporary password. It is randomly generated and could be numeric or alphanumeric. It can be used only once and has a short life-span time, beyond which it becomes ineffective. If it expires then a new OTP needs to be generated.

3. OTP Delivery

The OTP is sent to the user’s registered mobile number via an SMS. This SMS has to reach the user immediately because of the short life span of the OTP.

4. User Input

The user receives the OTP on the registered phone and enters it into the required field on the website or app wherever its input is needed.

5. Verification

The system verifies the OTP entered by the user against the one it generated and also ensures that the OTP is still valid.

6. Access Granted

If the OTP matches and is well within the valid time frame, the system grants access or approves the transaction and the user can move ahead with the transaction. If not, the user may need to request a new OTP and the entire process is repeated again.

The Security Features of SMS OTP Verification

• Encryption

The OTP is encrypted during transmission to prevent misuse by hackers. In other words, the OTP is converted into a code that is unreadable by anyone other than the authorized recipient. It ensures that even if it is hacked during the transmission, it cannot be understood by the cyber-criminal.

• Expiry Time

OTPs have a short validity period to minimize the risk of unauthorized use.

• Unique Code

Each OTP is unique and not repeated.
