NodeBB is a modern and well-supported forum software package that offers great user experience. Unlike hosted forums, it allows developers to run the software on their own domain, providing UX and SEO benefits. To set up single sign-on (SSO) for NodeBB, developers need to create an application in an identity management system such as FusionAuth, which provides OpenID Connect (OIDC) support. The developer then configures NodeBB to use this existing system to provide SSO to users, allowing them to log in and post with the same username and password they use for other applications. This setup provides a better user experience and helps minimize the number of usernames and passwords users must manage. It also enables developers to control access to their applications from one screen, making both their lives and their users' lives easier.
