In this blog, I will share the importance of OTP technology. Let’s start the discussion with “the meaning of OTP technology.”

Understanding the OTP (One-Time Passwords) Technology

A one-time passwords (OTP) is a unique password that is generated once at a time, and every time you generate the OTP, it will be different. It is a unique code that you use to log into your online account and do important transactions online. This technology allows banks to provide their clients with safe transactions.

OTP has changed over the years, and there is not a single person who can be credited with its invention. The motive for the invention of OTP was to take security measures to ensure the best protection of digital information. One-time passwords (OTP) have developed and improved through many changes and research.

Here is a simple history of how OTP came to be:

Here, we explain the journey of OTP from six points:

  1. Back when computers and the internet were starting, people used regular passwords to protect their stuff. But these passwords were easy to guess, and that was a problem.
  2. As more people got online, hackers became smarter, and they could sometimes guess the passwords. So, experts started thinking about how to make security better.
  3. In the 1980s, they came up with something called hardware tokens. These were like little gadgets that showed a new secret code every minute.
  4. One of the famous examples of these tokens was RSA SecurID. It looked like a keychain and had a tiny screen.
  5. Over time, as smartphones became more popular, they found a way to do the same thing with apps.
  6. These codes, called OTPs, became common in many online services, like email and banking.

They make it really tough for hackers to get into your accounts because the code changes all the time.

Now, discuss “How does OTP Technology work?”

  2. Use the code: Now, you have to enter this special code where you need it, just like a regular password.

What situations make the use of OTPs right?

OTPs have become more common in the banking sector, where they are used for online banking, and in other economic areas as well. In this case, the client must first register with the bank using both their email address and cell phone number. This data was stored in the bank’s database. Should the client want to conduct business with the bank, they have to confirm their identity by providing their email address and mobile number. The bank provides the client with a one-time password through SMS after successful verification.
