Two factor Authentication is a process for security enhancement of the web platforms with which anyone can verify users of the website. There are a number of methods with which two-factor authentication can be done like send OTP (One time Password) through a voice call, bulk email and bulk SMS. But, the research says bulk SMS is the better option amongst these three as this is direct, most affordable and easy to reach option to send OTP on user’s mobile number. This can be done automatically through PHP or
JAVA SMS API or SMS APIs in other languages. You just have to integrate SMS API on the panel or tool like SendOTP developed by MSG91 automatically generate unique 4 or 6 digit code when a request come and send it to user’s mobile phone through
bulk SMS?.
