How to enable authentication on MongoDB (Tutorial)

A fresh install of MongoDB (and start without the --auth parameter) means that anyone that can connect to you mongodb server, can read and alter your data.

In this short tutorial we show you how to add a very basic form of authentication using an admin account.

With this video we try to make it easier for the people that prefer to follow video tutorials, rather than reading a documentation.

Sadly, you already put the processes before the tutorial which makes it hard to understand the steps. Maybe start from scratch next time?
