Example text

As the password length increases, you will end up reducing the number of common dictionary words that can be used as a potential password. NOTE For a variety of reasons, from the mathematics involved to common behavior of network users, a password that is seven or fourteen characters in length tends to be the hardest to crack. Since most users do not find a fourteen-character password easy to recall, seven typically is the magic number. REPEATING CHARACTERS Once you have decided on the password length requirements, you will need to decide if your users will be able to use repeating characters.

As an added precaution, you can encourage your users to make use of capital and lowercase characters as well. Some operating systems are case sensitive about usernames, but nearly all of them are case sensitive when it comes to passwords. For example, Je3na32 and je3na32 would be considered different passwords on most Windows, Linux, and UNIX-based systems. NOTE There is a common practice among Internet users to substitute certain numbers for certain letters. For example, e is replaced with 3, a with 4, s with 5, and t with 7.
