Hide auth on a client

[João Abrantes]

Hello Everyone.

I am building a client in python that will connect himself to a mysql server with a certain username and password. I will compile this client and turn him into a .exe . The thing is that I know that is possible to get the source of the code back from an .exe and I don't want anyone to know which username and password are they using because I don't want them to access to the mysql server without my client. Do you have any ideas of what can i do? Thanks!
