Password Security 101
Password Tips
"Strongest Security" = "Weakest Password"
Maintain security and reduce vulnerability: use strong passwords. Weak passwords increase your vulnerability to hackers and intruders, and increase the chances of identity theft. Strong passwords are critical for computer security.
Remember, it's not just you and your company that are compromised, it's also your customer. What is your liability?

Avoid Weak Passwords
Do not use:
- your first name, last name, or login name, in any form
- consecutive or repetitive numbers or letters such as 12345678 or AAAAAAAA
- adjacent keyboard letters such as qwerty or asdfghjk
- common and obvious letter-number replacements (e.g. replace the letter O with number 0)
- easily guessed personal information such as names and dates of yourself, family members, pets and close acquaintances
- easily obtained information, such as:
- address
- license plate numbers
- telephone numbers
- credit card or ATM numbers
- Social Security or Social Insurance numbers
- email addresses
- dictionary words, in any language, forward and backward
- popular book titles, movie titles, or phrases
- short passwords
Use Strong Passwords
- ideally, a strong mnemonic passphrase (easy for you to remember, without writing it down, but hard for others to guess)
e.g.
"It helps to use a rhyme or mnemonic."
The previous sentence could represent the reasonably strong password, "Ih2uar0m." - at least eight characters long
- a combination of upper and lower case letters, numbers, punctuation and other symbols
- quick to type, in case anyone is peering over your shoulder
Secure Your Passwords
- Never write down passwords.
- Never share your password with anyone. Protect all passwords as you would protect your bank PIN.
- Never store passwords unencrypted on your computer. Password management software is great for managing many passwords, but take great care to protect access to your password database with a strong password, access card or USB key! (Or better, a combination of these).
- Never type your password when anyone is standing nearby.
- Beware of phishing scams.
- Change your password frequently.
- Never use the same password in many places, especially online!
- Food for thought: Key clicks betray passwords, typed text
