Your site claims that my awesome password is in the dictionary. I checked the dictionary and 'qwerty1234' is not in it…

We are a computer security testbed, so please use a strong password. You may be reading this because you were told that your new password, 'qwerty1234', is in the dictionary. We don't mean the Oxford English Dictionary here. What we use is a large list of dictionary words *combined* with actual passwords that have been found in the wild. For example, the RockYou hack ended up revealing the unencrypted passwords of 32 million people (and about 14 million unique passwords). Since this list is one of the go-to lists for the bad guys, we use it too. This means that a lot of passwords that seem clever or obscure fail our test because someone else thought up the same thing. The longer your password, the less likely it is to be in the dictionary. Try combining multiple words mixed with numbers and symbols. That way you get an easy to remember password that also will pass our dictionary checks.
