This is a password system made for things like OSes. It uses a list system for things so you can do things like change the password or the interface depending on who is signing in. You can also do things like block people who are signed out, or just need to be blocked in general.
The link is right over here.
You can use this in your games and stuff, you don't have to credit, though it would be nice if you did.

Wow! Love this project! I love how the sign in system works. Just, if I ever made a project, I would probably NEVER make a project so nice it needed a sign in system! Great job!
