MongoDB, users and their passwords. Not sure how to create them?

Question

MongoDB

It is clear how to create collections, how to update and delete - it is also clear.
But I don’t understand how and where users are set with their passwords for accessing data.
If anyone knows, please describe.

Answer 1

db.addUser( { user: "Alice",
              pwd: "Moon1234",
              roles: [ "readWrite", "dbAdmin" ]
            } )
