- Dear $username,
-
- The login password you use for the account "$username" has been found to
- be insecure by the "Crack" password guessing program. You must change
- your password as soon as possible.
-
- Passwords which are not easily compromised by programs such as "Crack"
- are based upon non-dictionary words, hence any word which might appear
- in a dictionary, EVEN IF IT IS SUPPOSEDLY A OBSCURE WORD is unsuitable.
-
- Similarly, any password which is derived from your name, department or
- other personal information is unsuitable because it can be easily
- guessed.
-
- It is important that password security be maintained at a high level for
- the sake of ALL the people who use these computers. We thank you for
- your co-operation in this matter.
-
- Yours,
-
