Create Strong Passwords and Passphrases
Here are a few simple things you can do to improve the overall strength of your passwords and passphrases (memorized secrets).
Make Them Hard To Guess
- Hackers use content from social websites, compromised password lists, movie scripts, songs, etc., so avoid nicknames, pet names, birthdays, anniversaries, stuff that can be found about you on social websites, famous quotations, and predictable keyboard sequences.
- Don’t just add numbers or substitute special characters for letters – hacking tools check for these combinations.
Make Sure They Are Long and Complex
- The more characters your password contains the better. LBCC’s current standard is 16 characters with one upper case and one number.
- Passphrases are typically a better choice than passwords. In addition to being long and complex, they have the added benefit of being more memorable and easier to type than something like !a$5_Yx2. Just make sure it’s hard to guess.
Safeguard Your Account
- Use different memorized secrets on different systems and accounts.
- Use a password manager to assist with generating and retrieving strong passwords.
- Use 2 factor authentication (2FA) where available: Google, Facebook, Instagram, Twitter, and Amazon all support 2FA.
- Make sure your connection is secure so it doesn’t send your passwords or personal information unencrypted.
Since you really should be using unique passphrases for each site, password managers are an excellent means for keeping all of your passphrases safe. A small caveat: You must not forget your master passphrase to the password manger or you will have to reset all of your passphrases again.
As a general rule, you shouldn’t write down passwords or passphrases because it encourages bad behavior such as posting them on your computer screen or leaving them under your keyboard; however, if you must write one down (e.g., for your password manager), make sure that you:
- Store the paper in a safe place like a home safe, or your wallet.
- Destroy the paper as soon as using the passphrase becomes second nature.
- Refrain from storing passphrases on digital devices such as your phone, computer, tablet, etc. Once compromised, hackers scour devices for accounts and passwords.
Unfortunately, compromised accounts and password lists exposed by data breaches are freely available on the internet. In addition to identity theft, some phishing attempts, such as sextortion scams, utilize these resources to lure people into responding.
- Check if your personal data has been compromised by a data breach.
- Register to receive notifications if your account is exposed by future breaches.
- Get advice on how to protect yourself and what to do if your information is exposed.

Test the Strength of Your Memorized Secret
LastPass, a leading password manager vendor, provides a secure utility to test the strength of your memorized secret as well as suggestions for improving its strength.
Note: Strength meters have limitations since they do not account for user behavior or check against password lists, dictionaries, etc.
To maximize the utility of a meter, one must follow password creation best practices.
