Abstract
A method for generating one-time password (OTP) using a mobile phone registers a telephone number of the mobile phone on a website at first. A communication server generates a first random number and a second random number. Furthermore, the communication server generates a first OTP according to the first random number, and a subscriber identity module (SIM) card of the mobile phone generates a second OTP according to the second random number. The communication server checks if the second OTP is the same as the first OTP. If the second OTP is the same as the first OTP, the mobile phone has successfully logged onto the website.
