[FIXED] What is the "admin" database in mongodb?

Issue

I was practicing ont mongodb documentation : https://docs.mongodb.com/manual/tutorial/enable-authentication/

and I can't figure out if the "admin" database in the example is just a database created for the tutorial or if it is a built-in database made specifically for managing admin users.

Thanks in advance.

Solution

When you create a database in MongoDB you don’t have authentication enabled, the user has all the privileges and roles over that database, you even have access to the database remotely if the firewall doesn’t have port 27017 blocked.

There are two special databases admin and local, users of these databases can perform operations such as those mentioned in the document on other databases to which they have access. In a development environment it is convenient not to worry about users and passwords, however, when users interact with the database remotely on an application, it is essential to activate user authentication.
