Authenticated Embedding in MongoDB Charts is a feature that secures data visualizations by integrating with a site's existing authentication system, ensuring only authenticated users can view the embedded charts. The feature allows users to make sensitive information visible to authorized personnel while restricting access to unauthorized individuals, and can be used to contextualize data based on location for compliance reasons. To get started, users must enable authenticated embedding on their Chart and Data Source, create an authentication provider in Charts, and embed the chart in their application. The feature also enables the use of Injected Filters to make data relevant and compliant with local data security laws by restricting regional managers' read access to their local datasets.
