# Central Authentication and Authorization

**Central Authentication and Authorization** is a security framework that allows users to use a single set of credentials (such as the [[zentraler-nutzeraccount]]) to verify their identity (authentication) and determine their access rights (authorization) across multiple different web applications and services.

At the Universität Greifswald, this is implemented via [[shibboleth]], which streamlines access to both internal tools and external licensed resources.
