By default, MongoDB has no protection at all. Anyone can log in remotely without any account, which is really dangerous if you use it for programming.

MongoDB: A Document-Oriented NoSQL System, and an Installation Guide for Windows and Linux

But after actually using MongoDB, I found the two are quite similar. They differ a bit in principle, and NoSQL performs better. Of course, some things SQL can do, NoSQL can’t, so it comes down to the trade-offs and needs of each person. NoSQL itself isn’t what this post is about, though. This post introduces MongoDB and shows how to install it on Windows.

Later I looked it up online and learned that this is one of its features: Schema Free.
