In the present scenario internet usage and the online banking sectors are experiencing spectacular growth. The Internet is the fastest growing banking channel today, both in the fields of corporate and retail banking. Banks prefer their customers to use the online banking facility as it reduces their cost, primarily through labour costs. The online banking system addresses several emerging trends: customers’ demand for anytime, anywhere service, product time-to-market imperatives and increasingly complex back-office integration challenges. Online fraud has become major source of revenue for criminals all over the globe. The challenges that oppose online banking are the concerns of security and privacy of information. This has made detecting and preventing these activities a top priority for every major bank. The use of single-factor authentication, such as a user name and the password, has been inadequate for guarding against account fraud and identity theft, in sensitive online banking systems. In this paper we are going to analyze the QKD multifactor authentication in online banking systems
