security passwords

[Saturate]

I have come to find that you guys, shun people that ask to many questions, but I have been looking over MS3.0.3 and 4 and I have noticed one issue, neither one are truely secure, if you choose to sell your client any player can burn a copy. If you are online on your account, and another player signs on to your account the

Code:

'prevent dupe account

works decently, but I was testing all of the code and with a small hacking tool I made acouple of months ago using C++ you can manipulate the players accounts and take another players character and save it to there own account, trade the items to the other account, and then delete it... so I am wanting to write a seperate password system for the characters so you have to enter a pass for the account and a pass for each character. Kinda like a CD-Key from starcraft.
