We keep hearing from security "experts" that passwords can be cracked in no time thanks to fast processors. This is, however, total bullshit for any reasonably secure system because such a system will lock an account at least temporarily should the incorrect password be used more than a certain number of times. So I care not that you have a brute forcing system that can generate five bazillion passwords a second. Even a fairly loose system will lock your account for a few minutes after half a dozen attempts. This being the case your amazing password generating breast will take years to crack even a fairly simple password.
