We live in a digital world, where online transactions are no longer a trend, rather they have become indispensable. Nowadays, every person in one way or the other is online services for buying different products and services.

An OTP (one-time password) is an automatically generated string of numeric or alphanumeric characters. It is used as a mode of authentication to verify the users before a transaction or running a session in an app/ website. 

The OTP is generated from a 2FA security token and is delivered through an SMS. For safety reasons, the OTP is designed in a way that it would be valid only for a short period of time; after that particular period the users have to obtain a new OTP. 

There are three ways to send the OTP SMS:

  • Voice(Phone Call)
  • Email
  • SMS

Due to the technical intricacies, voice and email procedures are not much favoured. SMS is the most popular, simple, and reliable way to reach consumers.

Why Is It Beneficial?

  • It is the best way to validate the user in a simpler way, especially for banking transactions.
  • Bulk OTP SMS does not take more than 30-60 seconds to approve the user. It becomes invalid if the user forgets to put the given pin number at the specified time.
  • As soon as any transaction takes place, it notifies the user about the transaction.
  • It is relatively safe and secure when it comes to sending the bulk SMS. It deters the criminals from receiving secret codes.
