Setting User Data

Make sure you have Godot installed, preferably 4.2.2 or later, since the project was created in 4.2.2.stable. Open up the User Data folder and go to User.painoperatingsystemlogin which you can open with Notepad, make sure you set the Username to what you want the OS to display for logging in and also set the password to be what you want, make sure to write it down, or whatever you need to do to remember the password.

Make sure to test your login credentials by opening it up in Godot.

Until a settings window exists, this is how you change user data.
