Anyway I can make it so everyone can store files instead of just the owner?
I wanted to make it so everyone can store files in my project into a folder or something so they can continue to access there data. Right now it either won't save for another person, or the other person has to copy paste all the code or make a copy so it's there version. Was hoping I could get this to work so I could make a local multiplayer mode where people can access there accounts on the same device and compete.
Not with the approach you're currently taking. Using the built-in database won't work with multiple users either. I suggest you look into using an external database service such as MongoDB or similar to have persistent user data.
