Basic Password Safety
Perhaps this should have been the first post. I'd make it a pre-requisite for any actual 101 "class".
Issues abound with passwords, and most people use such simple passwords that they can be quickly guessed or are in the top few tested by cracking software.Don't...just don't.
1.) Do not use a short password. I recommend a minimum of 7 characters.
2.) Do not use any password found on the most commonly used passwords list
. If you do, you are begging to be hacked.
3.) Do not use common sequences, like "abcdef" or "lmnop" or "4567".
4.) Ditto with common dates (07041976), including your birth date/year, age, anniversary date, or birth dates of your children.
5.) Do not use words that appear in the dictionary - for any language. Especially do not use them in all lower case and appearing exactly (spelling, etc) as they do in the dictionary.
6.) Do not use the same password for all your accounts. Do NOT do it. One successful crack of your password on one account will give the person access to all your accounts.
A more exhaustive list
of do's and don'ts is a worthwhile read.
