if(!strcmp(hashPassword, PlayerInfo[playerid][Password], true))
{
    //Put what happens when the correct password is filled in.
}
else
{ 
    ShowPlayerDialog(playerid, DIALOG_LOGIN, DIALOG_STYLE_INPUT,""COL_WHITE"Login",""COL_RED"You have     entered an incorrect password.\n"COL_WHITE"Type your password below to login.","Login","Quit");
    return 0;
}

You were using the non hashed string to compare to, and you were mistaking with the return value of strcmp. Sorry I did not notice this the first time, it should work now.

Also don't use return ShowPlayerDialog, just because ShowPlayerDialog returns a value it doesn't mean it's the correct value, it just doesn't make sense. Return 0 (just ending the function) would be better in this case.

Edit: Kiroloss beat me to it, gotta love the wait between post time haha.
