Saw this link a while back, and it's got me split because in one way I think it's great info, on the other hand, it could be a bad thing.
It checks your password and tells you how safe it is. However, there's a note on the site that says "We could be stealing your password, but we're not, be careful where you enter your password".
Well, if you were stealing my password, do you think you'd say "I'm stealing your password?". Granted, having any password and not having any login information for anything at all is pointless, but it's still interesting to think how easy it would be to get people put it in their passwords.
I'd recommend if you're paranoid, don't type your password, but type something close. If your password is "William564", put in something similar instead. You'll get the same results.
I was a bit shocked to see how much can be cracked "instantly", but also quite happy to see my combinations run into the 100's of days to crack with a normal PC trying to crack it.
