I use the same account and password so it saves me time from changing my configs. Also I can remember it better. I only have one password for everything I do. So that's why I am concern when it comes to password stealers.
http://lky.coindog.net/Do not create an account here. They wanna scam your useraccount and password. I created one and it doesn't allow me to login. It's a fake site.
Not if you do as everyone should do, and use a different password for each site you have

So you are saying you using the same password on all your sites?
