So here's my problem, I want a system to work with signing in to my game I am making, so basically, I've heard of a file called a DLL file, "Dynamic Library Link" I think you can use it to sign in to a GMS2 game if you connect it somehow, so how would I for starting,

1. Get A login and Create login system, I will probably make my own version of steam to do so, create account, login, and you can purchase licenses for our games then login, so GMS2 checks for if you have that licence and it's connected to a password, if typed incorrectly via the license data connected to it will deny access to the game, it would look like this: `User license: "XansiVA", Logged in as: "XansiVA"` then access should be given to open the game, from the outside of the client, most likely similar to how when you open Diablo 3 it checks for a battlenet login and password!

2. Now I need a way from your password being correct and logged in on the "application" which would be similar to steam or battlenet, and NOT holding all of your passwords, so it can't be stolen !, it's simply checking if your logged in, now the license is inside of your account data, so inside of a system and not your computer so it grabs data, from the application/client and it's not copyable :D

3. (hopefully I can encrypt the DLL file TwT)

4. I also need a tutorial on how to use firestore extension for GMS2-
