What is full form of OTP?

The full form of OTP is the One Time Password . One-time password (OTP) is a unique security code generated by the verification network that provides users with an additional level of security for strong authentication.

It is an automatically generated numeric or alphanumeric string that authenticates the user for a single logon transaction or session. This password is only valid for one logon session or transaction in a computer system or other digital device. OTP avoids a number of the shortcomings of traditional (static) password-based authentication

One-time passwords are an easy and reliable form of two-factor authentication and are used to add a second layer of authentication. The risk of fraud is drastically reduced if the user does not just need to enter their username and password. One-time password (OTP) messages are unique for each user and each login on any digital device.

How one-time passwords are generated

OTP security tokens are microprocessor-based smart cards or pocket keychains that generate a numeric or alphanumeric code to authenticate access to a system or transaction. This secret code changes every 30 or 60 seconds depending on the configuration of the token. Mobile device apps such as Google Authenticator use a token and PIN to generate a one-time password for two-step verification.

OTP security tokens can be deployed through hardware, software, or on demand. Unlike traditional passwords, which remain static or expire every 30 to 60 days, a one-time password is used for one transaction or logon session. This prevents some form of identity theft by ensuring that the captured username / password pair cannot be used a second time.

OTP example:

Suppose you use Gmail and Google asks you to turn on 2SV, if you turn on 2SV you will get an OTP every time you log into your Gmail account, which will increase your security.
