Shibboleth is a Single Sign-On (SSO) system widely used in academic publishing to enable secure access to digital resources using institutional credentials. It allows users, such as students, faculty, and researchers, to log in to multiple platforms (journals, databases, e-books) with a single set of login credentials provided by their home institution. This system enhances user experience by eliminating the need to remember multiple passwords for different platforms and ensures secure, authenticated access to subscription-based content. Shibboleth is important in academic publishing because it simplifies access to scholarly materials, especially for large research institutions where hundreds of digital resources may be subscribed to. For publishers, integrating Shibboleth into their platforms expands their accessibility to users across different institutions, fostering wider dissemination of their content. Shibboleth is widely used by publishers like Wiley, Springer, and Elsevier to provide seamless access to academic content. The system also adheres to privacy and security protocols, protecting users' personal data.
