Needless to say I went and had a play and my results were much the same as Judy found (only much worse!).
My banking password was cracked in one second, and a password that I call my 'generic' password and use for everything that I don't think needs to be secure came back with a result of 237 years.
The one thing which this test does not take into account however, is the use of personally identifiable information such as names, kids names, DOB etc that a person may find out about you in order to crack your password.
Be all means go have a play, but remember to have a password that is also not easily guessed!
Oh yeah, I have chosen a new password...
7 billion years? Much better :)
