1.1 Introduction
One Time Password (OTP) is free from brute force, replay, and shoulder attacks. The codes may originate from different entropy attributes and schemes, such as true random and digital random number generators. Businesses, organizations, and academic institutions have adopted OTP methods for credit card transaction confirmation, recalling forgotten passwords, and validating web portal accounts. An OTP is a created secret word which just substantial once. It is an automatically produced numeric or alphanumeric string of characters that validates the client for a single transaction or login session. OTP security tokens are microprocessor based smart cards or pocket-size key fobs that produce a numeric or alphanumeric code to confirm access to the framework or string. This secret code changes each 30 or 60 seconds, contingent upon how the token is designed (Cognex, 2021).
