Server Database with txt doc

Unity Engine
1

I know you can get data from websites and stuff. But is there a way I can have text document that only I can update with data that can be updated in game? So for example if somebody made an account on my website and I got the information for the account. Then I added the information to a text file and that file updates over the server so that people can use there login information and sign into the game. Would I need a website for this or could I just use something within unity?

Also I want you to be able to login from a different computer so this has to be over the network.

Or is there another way to go about doing this?

Hi

i solved this problem with php and a little bit of javascript. Write me if you need the php script too. I’ll post my login script for Unity here so you can have a look at it. It’s not very well written but i hope you can get some inputs for your own.
