If you're using chrome and have your password saved you can find it back in the settings. You can google how exactly.
Don't know whether other browsers have the same feature, they might.
If you're still logged in to your account ingame, go to your toribash folder and open the tb_login.dat with notepad. You can see your password there.
If you can't find it back in the settings, try to pm an admin, they might be able to help.
