Single sign-on (SSO) solutions are authentication tools that allow users to access multiple applications or databases using a single set of credentials. Federation refers to the linking of IT systems, organizations, and personal identities with associated credentials and repositories. SSO solutions simplify the login process by enabling seamless access to applications, portals, and servers, eliminating the need for multiple logins. The primary goal of SSO software is to enhance user convenience while navigating across various applications, while also easing the workload for IT administrators and developers by centralizing access management. SSO solutions typically route logins through an SSO server, connecting desired applications. They often include features like dashboards for easy navigation, cloud-based applications, directory integration, and mobile access for remote users. While there is some overlap between SSO software and other solutions like cloud identity and access management, password management, and user provisioning/governance software, SSO products are specifically designed to focus on secure enterprise access to applications, servers, and databases, rather than managing data or passwords.
