Creating Administrative MongoDB User

First, access the MongoDB Shell.

Run the following command to create a new user and set the password for the user.

db.createUser(
  {

        pwd: "SecurePassword",
        roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
    }
)

Output:

Successfully added user: {
  "user" : "mongoAdmin",
  "roles" : [
    {
        "role" : "userAdminAnyDatabase",
          "db" : "admin"
     }
    ]
}

Exit the mongo shell.
