Abstract : One Time Password (OTP) is a type of password that is valid for only one time use (use them once and throw them away). It is an automatically generated string of numbers that will authenticate a user for a single session or transaction. In this paper we propose a way of generating alphanumeric one time passwords (OTPs) using automaton theory with linear functions which enhances the level of security.
