Digitalization has infiltrated all sides of modern culture today. One of the most important aspects of making this procedure secure is authentication. Cyber criminals are putting in a lot of effort to break into existing network channels and launch destructive assaults. When it comes to businesses, information is a valuable resource. The question here is how to safeguard crucial information. This takes into account a variety of features of a society that is commonly referred to as hyper connected, such as online communication, purchasing, access rights control, and so on. We shall cover the ideas of MFA and KBA, or Multi-Factor Authentication and Knowledge Based Authentication, in this study article. The goal of MFA and KBA is to be utilised for human-to-machine interactions, providing an easy-to-use and secure validation mechanism while gaining access to the service. We will also look into the existing and evolving factor suppliers (sensors) that are used to authenticate a user in this study. This is a critical tool for safeguarding data against malicious insiders and outsiders. The basic purpose of access management is to give authorised users access to a service while simultaneously preventing unauthorised users from accessing it. To ensure access management, a variety of strategies can be used. In this paper, we will cover various strategies for ensuring enterprise-ready access management, with a particular emphasis on multifactor authentication. We'll also discuss how knowledge-based authentication fits into multi-factor authentication and how it may help businesses protect their data from cyber-attacks. Finally, we'll talk about the future of MFA and KBA.
