Alphanumerical OTPs: The characters in the OTP are a mix of both numbers and alphabets.Numeric OTPs: All the characters in the OTP are numbers only.In general, One Time passwords can be classified into two types:

In this article, we will learn how to generate One Time Passwords only. Generally, the client and server(generates the OTP) use time-synchronization algorithms so that the user is validated whenever OTP is gentered within a given time frame. So let us start with the fundamentals of One Time Password (OTP) generation. This technique is very simple yet a powerful way of verifying users. It is used almost in every banking transaction.

The main role of One-Time Password (sometimes analogously used as One Time Pin) is to authenticate a user for a single session or transaction. Most of the two-step authentication or two-step verification methods use One-Time Passwords. Yes, it can also be used to capture the user's OTP at that point of time, but that OTP cannot be used for the next time to log into the account. Keyloggers (software or hardware which can be used to capture strokes on the keyboard of a device) help to capture static password typed by the user.One Time Passwords provide better security over static passwords because OTP's have expiry time which makes it harder for any hacker or attacker to crack the password within the expiry time of the OTP.

There are many problems with static passwords, some of them are listed below Static passwords are the passwords that we associate with our user-id or email-id while registering for any website or mobile app. Most of the web applications and even mobile applications are using one time passwords as the first step of verifying authenticity of a user because there are many issues with static passwords. One Time Password or OTP is one of the security mechanisms used in modern applications. And hence, one should focus on security from the time of inception of any application idea. With so much data being generated, security has become the pillar stone for almost every technology/application. With the rise of technologies like Internet Of Things (IoT), Cloud and Big Data we have seen applications in the recent past which are making our lives better with each passing day.
