How to automate password in IE 4 0?

Any pattern in a password makes guessing (automated or not) easier. As of October 2005, employees of the UK Government are advised to use passwords of the following form: consonant, vowel, consonant, consonant, vowel, consonant, number, number (for example pinray45). Apparently upper and lower case do not matter, and this form is called an Environ password. The pattern of alternated vowel and consonant has probably been suggested so that the result will be somewhat pronouncable; it is a considerable reduction in the "randomness" of the generated password and is a reduction in security as a result, as is the restriction to letters and numbers.
