Hi @Alex_Chow , no problem! Happy to answer any questions.
- You can configure and enable IP access lists for the Atlas UI in Organization Settings. Feel free to read more specifics in our documentation: Manage Organization Access - Atlas - MongoDB Docs
- MongoDB requires a database user for any cluster connection. Data Explorer securely manages access behind the scenes for users, and it still follows this same paradigm. If you’d like to learn more about the database user connecting to clusters in your Atlas project, Data Explorer user activity can be analyzed the same way as activity performed by any other database user via server logs or database audit logs.
