Passwords

Creating a secure password

You should follow these guidelines any time you need to set up a new password. No matter how trivial or irrelevant it may seem, the need for a secure password is always of high importance.

Requirements

  • Your password must be at minimum 7 characters and must include at lease three characters from the groups below.
    • Lowercase letters – a, b, c,
    • Uppercase letters – A, B, C,
    • Numerals – 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
    • Non-alphanumeric (symbols) – ( ) ` ~ ! @ # $ % ^ & * - + = | \ { } [ ] : ; " ' < > , . ? /
  • Combine letters, numbers, and symbols. The greater variety of characters that you have in your password, the harder it is to guess.
  • Must not be based on dictionary words
  • Do not use your birth date, SSN, pets name, child’s name or other words that can be easily guessed.
  • Do not keep you password written on a piece of paper under your keyboard, on your monitor or in your drawer. A good hacker can find clues that will eventually lead to him/her breaking most passwords within 5 feet of the computer.
  • Do not share your password with others. Everyone should be issued a password and should be using their own.
  • We strongly suggest using one password per site you have an account on, DO NOT reuse passwords. This is the #1 weakness with passwords.

Examples of Bad Passwords

Using a Linux Command Line to auto generate passwords

If you are good at remembering passwords and have access to a Linux machine, you can use a command line utility called pwgen. You can specify the length of the password and the number of passwords you want to generate.

You can install it by typing:

sudo apt-get install pwgen

To generate passwords you type pwgen -y

pwgen -y 15 8

Which will generate 8 15 character passwords like:

For WiFi passwords, we suggest using a 64 character one with WPA2, something like:

Ooze6ophai'gh4Chahmo-Mapoh>ng0eeyoosh0soo>g8eerao~l*eide1iex1aex

How do I remember all my passwords?

I use LastPass password manager…. It generates secure passwords and stores them for you so you don’t need to remember but one password, the master one..
