Are you finding The Best OTP SMS Service, Providers? If yes, then this blog would be helpful for you!

Before we go into that, let’s get a few things straight.

With the advent of technology, OTP (One-Time Password) SMS Services have become a quite common term these days, but its origin in India can be traced back to 2011. It was the time when RBI laid new guidelines for Go Air customers making payments by credit/debit card. The guidelines stated that Go Air customers making payments through debit/credit cards need to have a mandatory OTP. Since then, OTP services gained momentum in the Indian market and are now extensively used by financial organisations and businesses like banks, e-commerce portals, websites, etc. The reason for using this service is the high security that it provides when dealing with any transaction by adding an extra layer of protection to them.


Now, let’s look into what exactly is an OTP SMS.  A One-Time Password SMS or an OTP message in layman’s language is a group of numeric or alphanumeric characters automatically generated for a single login attempt.

The purpose of using an OTP SMS is for authentication. The OTP SMS is sent to the user’s phone which is then entered by the recipient to confirm his/her identity. It is valid for only a specific time period and for one-time login access. This is useful in minimizing the risk of fraudulent login attempts and thus, reducing the risk of getting data stolen.
