Authentication, Authorization, and Common Errors
Understand the difference between authentication (verifying user identity) and authorization (controlling user actions) in MongoDB, and how to enable authentication, create users, and handle common errors.
Authentication verifies the identity of a user (e.g., username and password). Whereas, authorization determines what actions an authenticated user is allowed to perform (based on roles and permissions). Authentication keeps unauthorized users out, and authorization limits what authenticated users can do.
