Cloud computing is a popular topic in the IT industry, but not much is known about the risks that come with this new technology and delivery model. Because cloud computing has a lot of useful features, many organizations use cloud storage to store their important data. Users can store their data remotely in the cloud and use clients to get to it whenever they need to. This technology offers services using one of three service models: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). This model makes it possible for users and organizations all over the world to share their important information and important computing resources. One of the main things that slows down the growth of this technology in the information technology (IT) industry is making sure that users can't get to these important resources without permission. Authentication is one of the most important ways to make sure that only the right people can use registered services. The goal of this paper is to find out what's wrong with different authentication methods and figure out how to fix them.
