The Single Sign-On (SSO) technique allows users to authenticate with multiple applications using a single set of login credentials. This reduces password fatigue and minimizes the number of support tickets created for IT teams. SSO enhances security by limiting exposure to security issues like keystroke probing and exposure, while also enabling additional functionality such as multi-factor authentication and anomalous behavior detection at the identity provider. In this tutorial, you'll learn how to design and implement SSO using Django and FusionAuth, an authentication and authorization platform. By following the step-by-step instructions, you can integrate your Django application with FusionAuth and enable SSO-based authentication for your users.
