WARNING: Using Password Checker with actual passwords indicates that you
trust this web site and
plain text transmission over the Internet. One way to reduce
possible risks, besides avoiding any current real passwords altogether,
would be to change each digit to a different digit and each
punctuation or symbol to a different punctuation or symbol. This will
yield a password of approximately the same strength and still allow the letters to
be compared against the dictionary, including the many variations
and permutations that are checked. If you have repeating or sequential
digits, replace them with different repeating or sequential digits.
Changing the punctuation, symbols, or digits could possibly cause an obscure
(to human eyes but not password cracking tools)
keyboard (e.g. "&*(" ) or ASCII collating (e.g. "]^_") sequence to be missed.
The very strict default settings originally used by Password Evaluator/Checker
have been relaxed to settings appropriate to long passwords (15 characters and up).
If you are checking short passwords, you should select the settings for 6
character passwords for any password less than 12 characters, or those for 12
character passwords for 12 to 14 character passwords. The original defaults
were designed to identify
any non random multi character components: words, repeats, sequences, well known
patterns, that can aid a cracker. These can be very important in passwords up to
8 characters, but as the passwords become longer, such components become less
important. As the new Words Only component of the Passwor Generator shows, good
passwords can be made from several "predictable" pieces. The only way to get
useful evaluations of such passwords, using Password Evaluator, is to set
the minimum dictionary word lenght to 6 or 7 and the maximum to 10 or larger.
This will stop the password checker from
identifing the multiple short words we know to be present, and allow it to
possibly find an obscure long word that is hard to see, and which makes the
password a poor password. In this case allowed dictionary words should be
reduced from 1 to 0.
