MongoDB Authorization

By default, a new MongoDB database doesn’t enable authorization, and has no users. MongoDB comes with default roles such as root, userAdmin, userAdminAnyDatabase when we install it.

The root is the superuser role that provides system-wide access to the user. It can also create custom roles using a combination of permissions.

To learn about authorization, we’ll create an admin user with the userAdminAnyDatabase role. Authorization is not required for the development.

The userAdminAnyDatabase role allows us to add or remove users for any database on MongoDB.
